The dramatic progress in biological and medical research
demands that microscopes do more than answer today's
needs. To be viable, they must also offer the performance
potential and system flexibility to accommodate tomorrow's
research needs. To date, only one microscope fulfills all
these demands – the AX70 Research Microscope
from Olympus. Offering uncompromising performance and
outstanding system integration potential, the AX70 is a
reference standard for future microscopes.

AX70 and it’s
Universal Photo System –
the ultimate combination for
fully automatic photomicrography.
The AX70 and its automatic
photomicrography system represent
the ideal combination for scientific
applications. Using the AX70 together
with the U-PHOTO Universal Photo
System provides a very advanced
level of microscope performance and
sophisticated photomicrography
capabilities. Combining the
mainframe and its corresponding auto
focus function with the U-AFPHOTO
and motorized units integrates
innovative technology with a system
that fully supports automated
photomicrography. This combination
offers fast auto focus in brightfield,
darkfield, fluorescence*, and Nomarski
Differential Interference Contrast*, and
provides automatic light intensity
adjustment for the objective in use as
well as automatic observation light
path selection. Flexible moving spot
measurement ensures optimum
exposure regardless of specimen
distribution. A built-in Super FL Auto
mode offers fully automatic exposure
control for fluorescence
photomicrography. And easy, flexible
framing is assured via the zoom
magnification system. By centralizing
operation with a multi-control box, the
entire procedure from observation
through photomicrography can be
effectively automated. The U-PHOTO
20/80 is also available from Olympus
for simultaneous eyepiece and video
camera observation.
*The Auto focus can be activated by inserting an
optional memory card in fluorescence and
Nomarski DIC microscopy.

Effective solutions to research
demands from a flexible system
geared to fulfill present and
future requirements.
The AX70 starts by offering all the
advantages of the proprietary UIS
optical system to provide the best
image quality possible – and adds
universal adaptability for rapid
changeovers between various
microscopic techniques. The specially
designed Y-shape frame assures
superb operator comfort. A choice of
illuminator systems suits a range of
different microscopic methods. And
the system's substantial frame accepts
heavy attachments for image
processing and photometry
applications. These and many other
advanced features boost the
performance of the AX70 and ensure
flexible system upgradability. Olympus
further maximizes system versatility
with various accessories including the
AX-REXBA to optimally balance
fluorescence for double-stained
fluorescing specimens. The broad
range of accessories available ensures
that Olympus answers every user
need. Thanks to these and other
significant advantages, the PROVIS
AX70 system accommodates
increasingly complex and multi-
facetted research and experimental
requirements.

The major drawback of conventional

Olympus solved this problem by

switching the light source from the
conventional mercury burner to a
halogen source. The twin-lamp
housing configuration on the AX70
makes the switchover between the
mercury burner and halogen source a
simple operation.
Quick excitation light switchover
– a convenient feature for various
photometry and measurement
applications.
Working in combination with the
OSP100-DNA photometry system, the
AX70 easily handles different
measuring methods using several
fluorescent indicators. These range
from 1-wavelength excitation/
1-wavelength photometry（1Ex1Em）to
2-wavelength excitation/2-wavelength
photometry（2Ex2Em）. Thus, the
AX70/OSP100 combination can
measure fluorescence intensities at a
single wavelength with dual-wavelength
excitation using the fura-2 or BCECF
indicator. These advantages make it
ideal for analyzing intracellular calcium
ion concentrations and pH values.

FISH and Fluorescence advantages
The PROVIS AX70 thoroughly addresses the concerns of Fluorescence
and Fluorescence In Situ Hybridization (FISH) microscopy.
•UIS objectives produce fully corrected primary images. This leads to
exceptional RGB image registration for high resolution CCDs.
•High N.A. fluorescence optimized Fluorite and Plan Apochromat objectives
deliver images of exceptional brilliance, contrast and resolution.
•The wide choices of filter systems satisfies every fluorescent label and
includes filter cubes for simultaneous multi wavelength excitation and
emission. In addition, filter systems can be tailored to future demands.
•Ready adaptability of filter wheels to the massive stand enables the use of
stationary multichroic beam-splitter emission filters with single, dual and triple
wavelength exciter. This approach renders the highest registration
accuracy.
•The chromatically corrected illumination beampath produces uniform
fluorescence over a wide field of view, encompassing the entire excitation
emission spectrum.
•Efficient heat and IR removal in the collector lens protects interference exciter
filters from unnecessary energy.
•The automation capability (RS232C/GPIB) of the PROVIS AX70 makes it an
ideal base for automated FISH imaging stations.
