Congratulations!
The New Leica M Series
Common to all microscopes is the Leica range of accessories. Whether you
need a variety of illumination types, a wide selection of objectives or the
Leica swinging-arm system – there is a solution for everything there!
The introduction of the Leica M50, M60 and M80 adds three new high-
quality routine stereomicroscopes to the proven M-Series range from
Leica Microsystems. The optical brilliance and the wide range of acces-
sories make them the ideal microscope for quality assurance and similar
industrial applications.
Do you already own stereomicroscopic equipment and are thinking of
switching to Leica? No problem! Leica M50, M60 and M80 fit into micro-
scope carrier with a diameter of 76 mm and are therefore compatible with
many suppliers. You can simply continue to use your components and add
the proven Leica stereomicroscopes.
Magnification in stages or zoom
The Leica M50 stereomicroscope includes precisely reproducible magni-
fication levels for repeated examinations, measurements, drawing or
photography of objects under absolutely identical conditions. The five
easily selectable positions can be set without removing the eyes from the
eyepieces. This ensures that your results remain comparable at all times
without great efforts.
The Leica M60 and M80 stereomicroscopes can be used for a wide range of
routine applications with the 6:1 / 8:1 zoom and switchable ratchet steps.
The large working distance and the brilliant imaging power shows you
the finest details of your specimens without losing your overview of large
workpieces.

The Modular Design: Everything is Relative
The Leica M series provides maximum flexibil-
ity in choosing equipment, thanks primarily to
the modular configuration and the compatibil-
ity that Leica has painstakingly maintained for
decades. The optics carriers, eyepieces, bases
and more can be combined in any way you
choose, allowing you to create the microscope
that best suits your needs.
Despite this, you will notice that the controls

Maximum Compatibility
Leica engineers were careful to ensure that the
new Leica M series—like its predecessors—
remains compatible with existing series. This
means that objectives, bases, tubes and so on
can be reused.
Tubes
The interface between the optics carrier and
the tube has remained the same, so existing
tubes fit the new M series. The new tubes are
designed for eyepieces with field number 23,
while the predecessor models were only
designed for field number 21, resulting in a
smaller object field.
Objectives
All objectives of this new generation have the
same reference focal length as the objectives of
the MZ generation. If you prefer, you can there-
fore continue to use the previous Leica objec-
tive series.
Eyepieces
The new M-series eyepieces have an audible
and tangible click to provide immediate feed-
back in case of accidental adjustment.

The Correct Interpupillary Distance
The interpupillary distance is correctly set if you
see a single circular image field when looking
at a specimen.
Adjusting the interpupillary distance
1. Look into the eyepieces.
3. Slowly approach the eyepieces with your
eyes until you can see the complete image
field without corner cutting.
2. Hold the eyepieces with both hands. Push
the eyepieces together or separate them
until you see a circular image.
If you are still a novice microscope user, you
may need a short time to become accustomed
to this. Not to worry—after a little while, it will
become automatic.
Reference value
The distance between eye and eyepiece
measures approx. 22 mm for 10/23B wide-field
eyepieces for persons wearing glasses.

Using the Eyepieces
The eyepieces form the connection between
the tube and the eye of the observer. Simply
push them into the tube and they are ready to
use.
If you do not wear glasses:
1. Hold the eyepiece firmly and rotate the
eyecups forwards counterclockwise.
If you wear glasses:
1. Hold the eyepiece firmly and rotate the
eyecups counterclockwise towards the rear,
as otherwise the viewing distance is too
great.
Each eyepiece offers a certain magnification
factor that has a determinative effect on the
total magnification. Furthermore, all Leica
eyepieces can be equipped with practical grati-
cules that enable measuring and quantifying of
specimens.
2. If an eyepiece is equipped with the inte-
grated dioptric correction, turn the value to
the "0" mark.
Dioptric correction
A built-in dioptric correction is available for
eyeglass wearers. For more information, refer
to page 39.
2. If an eyepiece is equipped with the inte-
grated dioptric correction, turn the value to
the "0" mark.
By the way, one benefit of viewing with
eyeglasses is a drastically lower risk of bacte-
rial transmission (see page 38). The soft mate-
rial of the eyecup also ensures that your glasses
will not be scratched, even if they contact the
eyepiece.

Health Notes
Potential sources of infection
Direct contact with eyepieces is
a
•
potential transmission method for
bacterial and viral infections of the eye. The risk
can be kept to a minimum by using individual
eyepieces or detachable eyecups. Eyecups can
be ordered separately. Please contact your
Leica partner.
Separate eyecups are an effective
way of preventing infections.

vision problems. The correction comprises
5 diopter settings.
Using the Dioptric Correction
1. Set the dioptric correction of both eyepieces
to the mid position ("0" diopter settings).
2. While wearing your glasses, look through
the eyepieces and focus on the specimen.
3. Rotate both eyepieces to the maximum
value of "+5".
4. Hold one eye closed and rotate the other
eyepiece in "-" direction until the specimen
appears sharp.

in the "–" direction until each eye sees the
object sharply imaged.
2. Select the lowest magnification and focus
on a flat specimen.
9. Select the highest magnification and refo-
cus if necessary.
Preparation
3. Select the highest magnification and read-
just the sharpness.
★
Move the lever of the video/phototube to
the "observation" position and open the
diaphragm.
Now, if you adjust the magnification from the
lowest to the highest level, the specimen is
always brought into sharp focus. If not, repeat
the process.
4. Select the lowest magnification again, but
do not look into the eyepieces.
6. Rotate the eyepieces counterclockwise
in the "+" direction as far as they will go
(+5 diopter settings).

Graticules
Use
2. Clamp the graticule on the insert, applying
moderate pressure. Ensure that the grati-
cule fits tightly.
4. You can now align the graticule by rotating
the eyepiece in the tube and then tighten-
ing it using the clamping screw.
Leica graticules make length measurements
and counting easier, particularly for work-
stations that are not equipped with a digital
camera and LAS software.
The Leica graticules for length measurements
and numbering are fitted in mounts and are
inserted into the eyepieces.
1. Screw the insert off of the eyepiece.
3. Screw the insert and graticule firmly into
place and replace the eyepiece in the tube.

ErgoTube 10° to 50°
ErgoTube™ 10° to 50°
Assembly
The ErgoTube™ with continuously adjustable
viewing angle from 10° to 50° allows for opti-
mum sitting posture. Users who work with the
same stereomicroscope can adjust the viewing
height to their height with a simple hand move-
ment. If the head posture is changed, the view-
ingheightcanalsobereadjustedwithouthaving
to adjust the height of the chair. Special long
tubes enable the user to maintain an upright
posture. In order to safeguard against ESD, the
ErgoTube™ has been constructed from anti-
static materials.
Assembly of the ErgoTube 10° to 50° is exactly the
same as that of any other tube (see Page 20).
Handling
1. Then grasp the tubes with both hands and
adjust the desired tilt.

Photography & Video
For most microscope users, digital documen-
tation has become an invaluable part of their
work. Research results can be presented in an
attractive manner; measurements on the digi-
tal image provide clarity and, in conjunction
with the motorized IsoPro™ cross-stage, even
images of large specimens can be captured
step by step and automatically joined to create
a new complete image.
Leica DFC cameras
Leica Application Suite
However, if you require absolute control
over the camera and need the capability for
measurement, evaluation and more in addition
to photography, the digital Leica DFC cameras
are exactly right for you. Together with the
Leica Application Suite, they provide virtually
limitless freedom of use. For additional informa-
tion about Leica cameras, refer to the camera's
documentation.
The "Leica Application Suite", or "LAS" for short,
is, as it were, the digital extension of the Leica
M series microscopes. In addition to capturing
images, it lets you control the microscope, illu-
minator, stages, cameras and more. For addi-
tional information, refer to the LAS online help.
Adapter
If camera control using the Leica Application
Suite is not required, conventional mirror reflex
and rangefinder cameras from third-party
manufacturers can be used. For this purpose,
Leica Microsystems offers a variety of adapters
that can be used together with the 50% and
100% trinocular tubes.

Photo Tubes and C-mounts
Application
If there is unwanted shading at the corners even
with a compatible C-mount adapter installed, it
can be corrected using the "Shading function"
of the camera software.
Cameras from third-party suppliers
All Leica DFC cameras are equipped with a
standardized C-mount interface. In turn, the
C-mount adapter for the respective trinocular
tube is connected to this interface. This adapter
creates a solid mechanical connection between
the microscope and camera and ensures opti-
mum rendering of the microscopic image on
the image sensor of the camera.
In addition to Leica DFC cameras with the stan-
dardized C-mount interfaces, you can connect
third-party cameras to the microscope using
a T2 bayonet adapter. To do so, instead of the
C-mount adapter, simply use the correspond-
ing SLR adapter with T2 connection. However,
these third-party cameras are not integrated
into the Leica Application Suite and have to
be operated using the corresponding software
from the camera manufacturer.
Alternatively, you can also use a C-mount
adapter with higher magnification. This primar-
ily avoids the critical border area of the field of
vision and concentrates on the center of the
field of vision.
Usually, the ideal is for the digital camera to
capture as much of the field of vision as possi-
ble, while excluding as much of the black edge
of the field of vision as possible. To do so, the
magnification factor of the C-mount adapter
must match the image format of the sensor as
closely as possible (see table).

Video/Phototubes HD F & HD V
The video/phototubes HD F and HD V are opti-
mized for adapting state-of-the-art digital
cameras to obtain perfect results for image
acquisition. The video/phototubes can be
combined with the binocular tubes and the
ErgoModules™ from the Leica ergonomics line.
A range of high-quality video objectives with
different self-magnifications and C-mount
allows for the selection of different cameras.
★
Three-dimensional observation with 100%
light in the binocular tube.
The HD F features a fixed separation ratio of
50% in the binocular tube and 50% in the photo
beam path. This allows the user to conduct
three-dimensional observations of the samples
in the binocular tube, manipulate and edit them
and simultaneously project the image live on
the monitor. Since the sensors of state-of-the-
art cameras are highly sensitive, the exposure
time for most applications is short in spite of
lower light intensity.
Videotube HD V
Separation ratios
The HD V allows for selecting three different
separation ratios:
★
★
50% light at all outputs, i.e. 50% light for
stereoscopic observation and recording at
50% light.
100% light in the right eyepiece for moni-
toring the object and 100% light in the
camera to have the maximum light for
the recording under extremely poor light
conditions.

The Different Types of Objectives
To meet the various requirements regarding
imaging properties, there is a choice of high-
quality interchangeable planachromatic and
planapochromatic objectives and also lower-
priced interchangeable achromatic objectives.
Achromatic objectives
Achromatic objectives with a long focal
length:
For special applications achromatic objectives
with long working distances and focal lengths
of f=100 mm to 400 mm are available.
The 0.32×, 0.5×, 0.63×, 0.8×, 1×, 1.5×, 2× achro-
matic objectives offer countless variants for
selecting the object field diameter, magnification
ranges and working distances (see page 63).
★
★
★
Achromatic objectives are particularly
suited for specimens with high-contrast
structures.
Planachromatic objective 1×
For the highest requirements for overall image
quality, we recommend equipping the micro-
scope with the 1× plan (flat-field) objective,
which returns sharp, contrast-rich object fields.
Flat-field (planachromatic) objectives are
particularly well suited for studying flat
objects such as wafers and thin sections.
With planapochromatic objectives, the
finest structures are visible with high
contrast. The sophisticated apochromatic
correction allows these objectives to attain
the highest color brilliance and fidelity.
