Health risks
•Workplaces with stereo microscopes
facilitate and improve the viewing task,
but they also impose high demands on the eyes
and holding muscles of the user. Depending on
the duration of uninterrupted work, asthenopia
and musculoskeletal problems may occur. For
this reason, appropriate measures for reduction
of the workload must be taken:
OOptimal arrangement of workplace, work
assignments and work flow (changing tasks
frequently).
OThorough training of the personnel,
giving consideration to ergonomic and
organizational aspects.
OThe ergonomic optical design and
construction of the Leica S stereo
microscopes are intended to reduce the
exertion of the user to a minimum.
•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
personal eyepieces for each individual or
detachable eyecups.

Congratulations!
Congratulations on obtaining your new Leica stereo microscope from
the S series. We are convinced it will exceed your expectations, as
this instrument embodies all the qualities you associate with Leica
Microsystems: excellent objectives, high-quality engineering, and
reliability. Furthermore, the modular design ensures that the Leica stereo
microscope adapts perfectly to your needs – no matter which accessories
you require for your tasks.
Thanks to the parfocal system with simultaneously large working distances
and object fields, you can always view your microscopic specimens
accurately – from the complete image to the finest detail.
Though the reliability and robustness of Leica stereo microscopes is
world-renowned, like any high-tech product, the Leica S series requires
a certain degree of care and attention. Therefore, we recommend that
you read this manual. It contains all the information you need regarding
operation, safety and maintenance. Simply observing a few guidelines will
ensure that even after years of intensive use, your stereo microscope will
continue to work as smoothly and reliably as on the very first day.
We wish you the best of success in your work! after all, you are now
equipped with the best tool!

Have a special request? Let us know!
Leica Microsystems enjoys an exceptional
reputation when it comes to devising customer-
specific solutions. If you have a special request
that cannot be met with standard parts, contact
your Leica consultant. They have a solution for
every application.
The Modular Design: Everything is Possible
The Leica S series provides a high degree of
flexibility in choosing equipment, thanks
primarily to the modular configuration and
the compatibility that Leica has painstakingly
maintained for decades. The optics carriers,
eyepieces, stands, and more can be combined
in any way you choose, allowing you to create
the stereo microscope that best suits your
needs.
Despite this, you will notice that the controls
and individual components do not differ
significantly. Whichever configuration you
choose, you will quickly feel right at home with
your new stereo microscope.

S7 E User Manual 11
What Your Stereo Microscope has to Offer you
The optical system of the S series stereo
microscopes consists of two beam paths
converging at 10°. The objective pairs of each
optical path are positioned close together, so
the stereo microscopes can be of very "slender"
design, especially towards the base of the
instrument. The advantage: The advantages
of this design are that it has a small space
requirement for use on bonders and in machine
applications, unobstructed access to specimens,
plenty of space for tools and a completely clear
view of the object field.
The Greenough system enables cost-effective
correction of aberrations such as chromasia,
image field curvature, and distortion with
minimal effort. In all S series microscopes the
optimum corrected center of the objective
ensures high image quality. This provides
superior optical performance with large, level
and undistorted fields of view and chromatically
optimized, high-contrast images.
Patented FusionOptics Technology
The S7 E features the Leica patented
FusionOptics technology and delivers you
finest details in 3D. While the right channel
delivers you a high-resolution image at the
largest possible numerical aperture, the left
channel presents an image with high depth of
field. This results in an image perception with
outstanding richness of details and exeptional
depth of field at the same time.
ESD protection
The Leica S7 E including its cold light source
and stand, are made from a highly conductive
material with surface resistivity of 2 ×1011 Ohm/
square, with a discharge time of <2 seconds,
1,000 V to 100 V.

eyepieces for eyeglass wearers.
The procedure for taking measurements
is described in the "Measuring" user
manual.
Inserting graticule(s)
1. Use the stereo microscope to determine
the side on which the scale is inscribed. The
scale must not appear reversed.
2. Remove the insert from the bottom of the
eyepiece and place it on the bench with the
knurled side down.
3. Hold the graticule by the edges to avoid
leaving fingerprints, and push it into the
holder from the side.
4. Replace the insert in the eyepiece and press
it firmly into place.
5. Insert the eyepiece in the tube and turn the
eyepiece in the tube to align the graticule
correctly.
Inserting Graticules

S7 E User Manual Assembly 20
You can use your S series stereo
microscope together with a fixed or
adjustable eyepiece. For models in which
a graticule is included in an eyepiece for
measurement or photography, two eyepieces
are necessary. We recommend that you also
equip the high-powered S APO with two
adjustable eyepieces.
Inserting the eyepieces
1. Push eyepieces as far as they will go into
the tubes.
2. Check that the eyepieces are seated firmly
and precisely in place.
Risk 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 personal
eyepieces for each individual or detachable
eyecups.
