1.2 IsoPlane SCT 320 Description
The IsoPlane SCT 320 (IsoPlane) is a 320 mm focal length spectrograph. Its advanced optical
design reduces astigmatism to zero, increasing spatial and spectral resolution dramatically over
traditional spectrographs. Large-diameter optics and interchangeable triple-grating turrets permit
operation from the UV to NIR with extremely low light levels at high, low or intermediate
spectral resolution. IsoPlane includes 32-bit microprocessor controlled scanning, built-in USB
and RS-232 interfaces, and a micrometer-controlled entrance slit. In addition, it has a direct
digital grating scan mechanism with full wavelength and grating control capabilities. The
IsoPlane works seamlessly with Princeton Instruments’ industry-leading CCD, EMCCD, ICCD
and InGaAs array detectors and Princeton Instruments’ LightField® with IntelliCal™ and
WinSpec data acquisition software packages.

mounting an accessory to the slit is as follows:
1. Place the accessory directly against the face of the slit body.
2. Using four (4) 8-32 screws normally provided with the accessory, secure the accessory to
the slit body.
Light sources fitted with light collection/focusing optics are normally factory-aligned to the
standard slit.
Note: In some instances with light sources, there is limited access to the bottom two screw holes. In this
case, Princeton Instruments provides special slotted holes in the light source housing to facilitate
mounting the source to the slit.
2.7 Turret Installation
If you have just received an IsoPlane spectrograph, you will need to install the grating turret. The
grating turret has been shipped in the same shipping box with the IsoPlane but is packaged in a
plastic container outside the IsoPlane housing to protect the gratings during shipment.
CAUTION
1. The optical surfaces in the spectrograph are extremely delicate and can be permanently damaged by
contact with solid objects as well as with most liquids and aerosols.
2. DO NOT TOUCH optical surfaces with anything. Wear thin protective powderless gloves to
minimize damage from body oils if you accidentally touch any optical surface, especially the grating.
3. Avoid talking or sneezing near optical surfaces. Do not breathe directly on them.
The following procedure is for the initial installation of a
grating turret. Observe proper optical handling procedures.

2.8.5 Height Adjustment of Image Plane
Note: This procedure should only be attempted by someone experienced in
aligning optical components and assemblies.
2.8.5.1 Overview
During the manufacturing process, the IsoPlane focal plane is
factory-aligned so that it is precisely centered on the optical
axis. However, in some instances when a CCD camera is
attached, the center pixel of the CCD camera may be located
slightly above or below the optical axis of the spectrograph.
In most applications this is not critical: however, if it is
important to have the exit focal plane image precisely
centered on the CCD, the height of the exit beam can be
adjusted using the procedure in this section.
Set Screw
Cap Screw
If you have an optical fiber and fiber adapter that can
precisely center the beam at the center of the IsoPlane
focal plane, then that can be used as a guide in positioning
the exit focal plane. If the IsoPlane is equipped with a
Figure 2-12. Height Adjustment Screws
standard 3 mm manual entrance slit or optional 3 mm
motorized entrance slit, you can also install the supplied 4 mm high slit baffle and use the 4mm
high image as a guide in positioning the exit focal plane. The adjustment is made by adjusting
the pair of push-pull vertical alignment screws as shown in Figure 2-12.
2.8.5.2 Data Acquisition Mode
During this adjustment procedure, the detector should be running in continuous mode so an image of
the source is displayed in the acquisition software. Continuous operation is necessary to provide
active feedback of the light source position as adjustments are being made. We recommend using a
mercury lamp with a center wavelength of 546.075 nm however other light sources and center
wavelengths can be used.
2.8.5.3 Required Tools
5/32” hex wrench
3/32” hex wrench
2.8.5.4 Adjustment Procedure
2. Determine if the image is HIGH or LOW on the detector array.
a. If the image is HIGH, alternately loosen the Cap Screw and tighten the Set Screw until
the image is centered about the center row of the camera.
Notes:
ADJUSTMENTS TO OTHER SCREWS MAY RESULT IN SEVERE MISALIGNMENT OF
THE INSTRUMENT.

IsoPlane® SCT 320 Manual
Version 1.B
2. Adjustments to the Cap and Set Screws should be small, approximately 1/8th-turn or less.
3. If the Cap Screw is adjusted 1/8th-turn in a counter-clockwise direction, then the Set Screw should
be adjusted 1/8th-turn in a clockwise direction.
4. If the initial adjustment does not move the image far enough on the CCD, repeat the adjustments
to the Cap and Set Screws as stated in Notes a.2 and a.3 above.
5. Several small adjustments are recommended.
6. At the end of the procedure the Cap and Set Screws should be tight.
b. If the image is LOW, alternately loosen the Set Screw and tighten Cap Screw until the
image is centered.
Notes:
ADJUSTMENTS TO OTHER SCREWS MAY RESULT IN SEVERE MISALIGNMENT OF
THE INSTRUMENT.
2. Adjustments to the Set and Cap Screws should be small, approximately 1/8th-turn or less.
3. If the Set Screw is adjusted 1/8th-turn in a counter-clockwise direction, then the Cap Screw
should be adjusted 1/8th-turn in a clockwise direction.
4. If the initial adjustment does not move the image far enough on the CCD, repeat the adjustments
to the Set and Cap Screws as stated in Notes b.2 and b.3 above.
5. Several small adjustments are recommended.
6. At the end of the procedure the Set and Cap Screws should be tight.
2.9 Single Point Detector Mounting Instructions
Single point detectors (such as the PD-438) mount directly to
the optional exit slit with mounting plate assembly of the
IsoPlane monochromator. Because the outcoming beam path
exits from the focusing mirror at 15 degrees to the housing, the
slit assembly is secured to a tapered mounting plate at the
exit port.
1. Position the detector so its labels are upright (the
optical axis is not vertically centered).
2. Mount the detector directly to the exit slit assembly
(already mounted to the tapered mounting plate at the
exit port) so its four mounting holes align correctly
with the tapped mounting holes of the slit assembly.
3. Insert the four 8-32 mounting screws and use a 9/64”
hex wrench to tighten the screws.
4. The detector should now be mounted correctly.

2.10 Spectrometer Calibration
Refer to the application software manual or the software help for information on calibrating the
data pixels with wavelengths.
2.11 Slit Width Adjustments in the Model 716-1 Manual Bilateral
Slit and the 716-MS Kinematic Slit
The slit width of each bilateral slit assembly (716 type) is adjustable from 0.010 millimeters to
3 millimeters (10 to 3,000 µm) by a micrometer knob located on the top of the slit housing. The
micrometer knob is graduated in 0.010 millimeter (10 µm) increments.
Each clockwise revolution of the micrometer knob increases the slit width 0.25 millimeters
(250 µm). For maximum reproducibility, the slit width should be set in a clockwise direction
(increasing slit widths) each time it is changed. Refer to the drawing below.
The micrometer knob should not be rotated below a reading of 0.00 or above 3.00. A micrometer
setting of less than 0.010 millimeters (10 µm) should not be used, because a stop is provided to
prevent the slit jaws from contacting each other.
Note: Damage May Be Done If Slit Jaws Are Opened Wider Than 3.0 mm.

controlled adjustments are made in 5 µm increments over the full range.
Full control of the slit, including automated bandpass setting, is integrated
into LightField® and SpectraSense™ software. The slit motor is only
energized when you send the command via the software to control it. When
the power to a spectrograph is turned off, the slit remains in the position to
which it was last set. This position is stored in nonvolatile memory allowing slit position to be
maintained with power on or off.
2.13 Internal Shutter Installation/Removal
An IsoPlane may be ordered with an optional internal shutter at the entrance slit.
This shutter is controlled either by a detector via a shutter cable from the
detector’s Shutter connector to the Shutter connector on the IsoPlane or by an
Shutter Control box (Model SHC-EXT) available from Princeton Instruments.
2.13.1Installing an Internal Shutter
1. Using a 9/64” hex wrench, unscrew the four socket head screws that secure the Turret
Compartment cover to the top of the IsoPlane. Lift the cover and screws off of the
IsoPlane and set them aside.
Screws
3. Use extreme care so as not to touch the grating surfaces.
4. Mount the shutter assembly on the two socket head screws above
the entrance slit. You may need to back out the screws about five
turns.
5. Use the 9/64” hex wrench to tighten down the screws.
6. Connect the shutter cable to the connector in the floor of the
IsoPlane. Make sure the connector on the cable

2.13.2Removing an Internal Shutter
If you are planning to use a PI-MAX detector (or other detector without an external shutter
control connector) and the IsoPlane has an internal shutter, you will either have to remove the
shutter or control the shutter via a Princeton Instruments SHC-EXT external shutter control box
if one is available. This is because there is no way for these detectors to keep the shutter open or
to open the shutter during an acquisition. The following instructions step through the removal
process.
1. Using the 9/64” hex wrench, unscrew the four
Shutter
socket head screws that secure the Turret

2.15 Turret Interchange
Read and follow the instructions in this section only if you have ordered more than one turret for the
IsoPlane. Otherwise, you never have to interchange turrets.
The IsoPlane is supplied with one on-axis mounted triple grating turret assembly, but you may
order up to three (3) grating turrets for the spectrograph. If you have multiple turrets (2 or 3), the
built-in sensing mechanism will auto-identify for the software which grating turret is installed.
You may, however, want to label the turrets (for example, with the spectral range used).
CAUTION
1. The optical surfaces in the spectrograph are extremely delicate and can be permanently damaged by
contact with solid objects as well as with most liquids and aerosols.
2. DO NOT TOUCH optical surfaces with anything. Wear thin protective powderless gloves to
minimize damage from body oils if you accidentally touch any optical surface, especially the grating.

Chapter 3 Operation
3.1 Introduction
This chapter reviews how to enable the control of an IsoPlane and Princeton Instruments detector
by either the LightField (64-bit) or WinSpec (32-bit) software. This chapter also points out how
to perform alignment using the software. Further information about operating the system can be
found in the appropriate software manual or help file.
Warnings:
1. A PyLoN with an internal shutter or a SPEC-10 with an internal shutter CANNOT be used with an
IsoPlane spectrograph.
2. If the detector has a flange mount and has an internal shutter, DO NOT USE the Shutter connector
to drive a shutter internal to an IsoPlane. If both the detector and spectrograph have shutters, the
IsoPlane shutter will have to be removed or a Princeton Instruments SHC-EXT Shutter Control Box
3.2 Pre-Operation Checks
Before starting the operating software (LightField or WinSpec, for example), confirm that:
The detector is mounted to the IsoPlane.
The detector and IsoPlane are connected to the computer via the appropriate
communications cables.
The detector and IsoPlane are powered on.
If the detector is LN-cooled, the Dewar has been filled.
3.3 Initialization
When power is turned ON to the IsoPlane, it initializes to a wavelength of 0.0 nm for grating
number 1. If the power is switched OFF and then ON again to the IsoPlane, it will re-initialize.
Initialization gives the system a reference, or starting position to keep track of wavelength
position, grating location, and other parameters. Alternative start-up parameters can be
programmed if the factory defaults are not suitable (see Appendix A).

3.4 LightField
Start LightField after making sure the detector and IsoPlane are connected to the computer and
are turned on. When LightField boots it will look for available devices and will load their icons
in the Available Devices panel. Before you can design a new experiment or run an existing one,
the appropriate device icons must be dragged into the Experiment Devices panel. Once there is
at least one device, the Experiment Settings panel will be populated with expanders for groups
of experiment settings.
Note: If the IsoPlane (SCT-320) icon is the only device in the Experiment Devices panel, the
Spectrograph expander will be the only expander in the list. When you drag a detector into the panel, the
Calibration expander and all of the detector- related expanders will be displayed.

3.4.2 Perform Alignment
Because the detector is mounted directly to the mounting plate on the IsoPlane, the rotational
alignment and focusing operations are different from the way these operations are performed for
an Acton SP Series spectrograph. The following information assumes that you are familiar with
the locations of the mounting plate, Micrometer Compartment, and the locking set screw. If not,
refer to earlier sections of this manual.
1. Mount a light source such as a Princeton Instruments Hg and Ne/Ar Dual Switchable
light source in front of the entrance slit.
2. With the IsoPlane properly connected to the computer, turn the power on, wait for the
spectrograph to initialize.
3. With the detector mounted to the spectrograph and connected to the computer, turn on the
power and wait for the detector to initialize. If the detector is LN-cooled, the Dewar
should be filled.
4. Start the application software. Because you are using LightField, you will need to drag the
icons for the detector and the IsoPlane into the Experiment Devices area.
5. Set the spectrograph to 500 nm if using a mercury source or to 0.0 nm if using a
broadband source.
6. Wait until the detector locks at its default temperature.
7. Using a 9/64” hex wrench, loosen the four screws at the corners of the detector mounting plate.
8. Select the Align Spectrometer function from the Experiment menu to open the
Spectrometer Alignment dialog. This dialog describes the changes that LightField will
make to the current setup to assist you in performing rotational alignment of the array to
the spectrograph's optics. When you click on the Begin button, the modifications are
made and continuous live data will be displayed as you rotate the detector.

9. Click on the peak you will be monitoring for the alignment. This will display the data
cursor, which you can position at the top of the peak. Since the data cursor spans the
ROIs (graphs), you can use the data cursor as your vertical reference.
10. Slowly rotate the camera until the peaks align in all of the ROIs.
Alternatively, you can acquire an image, display the large data cursor, and compare the
vertical bar to the line shape on the screen. Rotate the detector until the line shape on the
screen is parallel with the vertical bar.
11. After completing the rotational alignment, click on the Stop button.
12. Re-tighten the four mounting plate screws.
13. Using a 9/64” hex wrench, remove the cover from the Micrometer Compartment.
15. Click on Run, and while continuously acquiring data, adjust the micrometer until you
maximize the intensity level and minimize the FWHM of a selected peak or peaks. Note
that the Peak Find function (for the graph selected by the cursor) is automatically turned
on to help you identify peaks and view FWHM widths.

3.5.3 Perform Alignment
The initial alignment described in this section assumes that you have already connected and
turned on the detector and spectrograph, have opened WinSpec, and identified the detector and
spectrograph. After you have aligned the optics the first time, you may want to repeat the process
to fine tune the alignment.
1. Mount a light source such as a Princeton Instruments Hg and Ne/Ar Dual Switchable
light source in front of the entrance slit.
2. From the Main menu bar, open the Spectrograph menu, select Move, choose the grating
to be move, and then set it to 500 nm if using a mercury lamp or to 0.0 nm if using a
broadband source.

3. Set the slit to 10 µm at a minimum. If necessary, adjust the Exposure Time to maintain
optimum (near full-scale) signal intensity.
4. Wait until the detector locks at its default temperature. If the detector is LN-cooled, it
should have been filled after the detector was powered ON.
5. Turn on Focus mode.
6. Adjust the rotation alignment. First, use a 9/64” hex wrench to loosen the four screws at
the corners of the detector mounting plate. While watching a live display of the spectrum
displayed as a graph, select a peak to monitor and then rotate the detector (up to 4 degrees
of rotation are possible). The peak will go from broad to narrow and back to broad. Leave
the detector rotation set for the narrowest achievable peak.
Alternatively, take an image, display the horizontal and vertical cursor bars, and compare
the vertical bar to the line shape on the screen. Rotate the detector until the line shape on
the screen is parallel with the vertical bar.
Another technique is to set up three ROIs (one at the top, middle, and bottom of the
array) with 10 rows binned for each via the Experiment Setup|ROIs tab, Then change
the data display via the Display Layout dialog, so that 3d Graph is selected (General
tab), the Z Axis Endpoints (3D Layout tab) are %X = 0 and % Y = 40, and the Save as
Default check box is checked. Click on OK. While running in Focus mode, you should
see three stacked graphs. Aligning the large cursor with a prominent peak, rotate the
detector until the peak aligns with the cursor in all three ROIs.
7. After completing the rotational alignment, tighten the four mounting plate screws.
8. Remove the cover from the Micrometer Compartment.
9. Using a 3/32” hex wrench, loosen the locking set screw.
10. While continuously acquiring data, adjust the micrometer until you maximize the
intensity level and minimize the FWHM of a selected peak or peaks.
11. Tighten down the locking set screw.
12. Place the Micrometer Cover on the spectrograph. Replace and tighten all of the cover
screws.
13. Then stop acquisition.

Appendix A Using the Monochromator Control Software
A.1 Introduction
As has been previously mentioned in this manual, the Acton IsoPlane spectrograph can be
controlled using Princeton Instruments’ LightField, WinSpec, or SpectraSense software. It can
also controlled from a computer using the supplied Monochromator Control software via the
RS-232 or USB interface. The information on how to do this is provided in this appendix.
A.2 Install the Monochromator Control Software
Use the install disk shipped with the monochromator to install that software on your computer.
The icon for this software on your computer screen is labeled MonoControl.
A.2.1 Monochromator Control Application Software
The Monochromator Control software is a stand-alone Acton software program for basic
scanning and calibration. Utilities for grating updates and communications are also included.
Normally, the software is installed in the directory C:\Program Files\Princeton
Instruments\MonoControl. This directory contains the subdirectories Bin and Data. The Bin
directory contains the executable code for the program.
Upon installation, a Monochromator Control icon is usually placed on the desktop for starting
the software. If this icon is not on the desktop, check for the program in the Windows Start
menu\Programs or go directly to the MonoControl\Bin directory and start the software there.
When the Monochromator Control software loads, there is a main screen with selections for
monochromator operation and for various setup functions. (If the buttons are grayed out, exit the
program, connect the IsoPlane, wait for it to initialize, and then restart the program.) Click on the
Operation button and a screen will come up which allows for basic control of the
monochromator wavelength. All functions of this software are described in the Monochromator
Control software manual supplied on the Monochromator Control software install CD.
A.3 Connecting the IsoPlane to the Computer
The IsoPlane is designed for operation by computer using RS-232 or USB, control that enables
wavelength scanning at a pre-set linear scan rate, change of scanning speeds, grating selection,
rapid GOTO wavelength positioning, change of grating turrets, and “jog” wavelength
positioning. Refer to the Monochromator Control software for Windows for operation with a
computer.
A.4 Controlling the IsoPlane Spectrograph at the Command
Level
Although it requires more programming on the user’s part, the spectrograph can also be
controlled with direct commands through its USB 1.1 port or RS-232 port. The same command
set, listed below, is used for both RS-232 and USB.
Commands can be sent as single commands or grouped in strings of commands. All commands are
single words (contain no spaces) and all commands in a string are separated by at least one space.
39
Download from Www.Somanuals.com. All Manuals Search And Download.
40
IsoPlane® SCT 320 Manual
Version 1.B
Parameters, if needed, precede the command and are separated from the command by at least one
space (e.g., 546.07 GOTO).
For RS-232 operation, the port set-up is 9600 baud, 8 data bits, 1 stop bit and no parity. A convenient
tool for trying out this mode of operation is the program HyperTerminal supplied with the Windows
operating system. The USB 1.1 port with the driver supplied also shows up as and is treated like a
com port – although a very fast one. All commands or strings of commands must be terminated with
a carriage return (0D hex). The spectrograph responds to a command when the command has been
completed by returning the characters OK followed by carriage return and line feed (hex ASCII
sequence 20 6F 6B 0D 0A). The default condition is to echo each character that is sent to the
spectrograph with the RS-232 interface and to not echo the commands when using the USB
interface. When sending a command or string of commands, it is important to wait for the
spectrograph to complete the processing of that command string before sending another command.
A.4.1 Spectrograph Wavelength Movement Commands
GOTO
Goes to a destination wavelength at maximum motor speed. Accepts
destination wavelength in nm as a floating point number with up to 3
digits after the decimal point or whole number wavelength with no
decimal point.
<GOTO>
NM
Same as GOTO (For compatibility with software written for previous
Acton SP series models.)
Goes to a destination wavelength at constant nm/min rate specified by last
NM/MIN command. Accepts destination wavelength in nm as a floating
point number with up to 3 digits after the decimal point or whole number
wavelength with no decimal point.
<NM>
>NM
Same as NM (For compatibility with software written for Acton SP series
models.)
Similar to NM except it returns control to user immediately rather than
waiting for completion of spectrograph wavelength move. Can be used
with ?NM or MONO-?DONE below. This command must be terminated
with MONO-STOP listed below.
Note: Use the NM command when communication with the monochromator
during the scan is not required.
?NM
Returns present wavelength in nm to 0.01nm resolution with units nm
appended.
e.g., ?NM 300.00 nm
MONO-?DONE
MONO-STOP
Used with >NM command to determine if monochromator has reached the
destination. Returns 0 if move is not complete, 1 if move is complete.
Stops the monochromator wavelength move after use of the >NM
command.
NM/MIN
Sets the scan rate in nm/min to 0.01 nm/min resolution with units nm/min.
?NM/MIN
Returns present scan rate in nm/min to 0.01 nm/min resolution with units
nm/min.

A.4.2 Grating Control Commands
GRATING
Places specified grating in position to the wavelength of the wavelength
on the present grating. Up to nine (9) gratings are allowed on three (3)
turrets. This command takes a grating number from 1 - 9.
IMPORTANT NOTE: This command assumes that the correct turret is specified
by the TURRET command. For example, using grating numbers 1, 4 and 7 will
place the first grating on the installed turret into that position and call up the
parameters for the grating number specified.
?GRATING
Returns the number of gratings presently being used numbered 1 - 9.
?GRATINGS
Returns the list of installed gratings with position groove density and
blaze. The present grating is specified with an arrow.
TURRET
Specifies the presently installed turret or the turret to be installed.
e.g., if installing the second turret, issue the command 2 TURRET to
insure using the correct parameters.
?TURRET
Returns the correctly installed turret numbered 1 - 3.
The following command is used for grating installation by Acton part number:
INSTALL
Installs new grating parameters into the non-volatile memory of the
IsoPlane monochromator. Uses the part number of the grating to specify
the parameters.
e.g., 1-120-500 5 INSTALL places a 1200 g/mm grating blazed at 500 nm
into the second grating position on turret number 2.
The following commands are used for grating installation by grating parameters:
SELECT-GRATING Specifies the grating number to be installed 1 - 9.
G/MM
Specifies groove density of grating to be installed in g/mm.
e.g., 1200 G/MM
BLAZE
Specifies the blaze wavelength and units of the grating to be installed with
7 characters of the user’s choice. Unlike other commands, this command
is issued before the parameters. After the command is issued, the IsoPlane
responds with ““ . Seven characters are then entered (these may be
numbers, letters, spaces or special characters).
UNINSTALL
Used to remove a grating and its parameters from the IsoPlane
non-volatile memory.
