Thank you for your confidence in our product. We wish you much
enjoyment and success with your new EZ5 stereomicroscope from
Leica Microsystems.
The new Leica EZ5 is an exciting addition to the extensive product
range offered by our Swiss Stereomicroscopy business unit. The
Leica EZ5 has been designed specifically with a view to OEM appli-
cations. In order to safeguard against ESD, the entire stereomicro-
scope – including the optional cold light source and the stand – has
been constructed with antistatic materials.
While developing the Leica EZ5, we took the greatest care to ensure
that its operation would be simple and self-explanatory. Even
so, please take a little time to read the accompanying operating
instructions. This is the best way to familiarize yourself with all the
features of your stereomicroscope and use it to its full advantage.
And if you have any questions, please contact your Leica repre-
sentative or Leica Microsystems (Switzerland) Ltd., Heerbrugg,
Switzerland. We are gladly at your service. CUSTOMER SERVICE is
a big thing with us – before and after the sale (see page 36).

Workplaces equipped with stereomicroscopes facilitate and
improve the viewing task, but they also impose high demands on
the eyes and holding muscles of the user. Long periods of uninter-
rupted activity may cause asthenopic complaints and injury to
the musculoskeletal system. Appropriate measures should be
adopted to reduce physical stress:
• optimal arrangement of workplace, work assignments and
work flow (changing tasks frequently).
• thorough training of the personnel, giving consideration to
ergonomic and organization aspects.
The ergonomic optics concept and the design of the Leica EZ5
aim to limit the strain on the user to the lowest possible level.
Direct contact with eyepieces is a potential transmission method
for bacterial and viral infections of the eye. Users should be made
aware of the potential risk of infection. This risk can be minimized
by using personal eyepieces or removable eyecups (see page 19).
Eyecups can be purchased separately. For more information,
contact your Leica partner.

Greenough based
optical system
The optical system of the Leica EZ5 consists of two beam paths
converging at 10°. The lens pairs of each optical path are posi-
tioned close together, so the stereomicroscope can be of very
"slender" design, especially towards the base of the instrument.
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 aber-
rations such as chromasia, image field curvature, and distortion
with minimal effort. The new Leica EZ5 uses the most corrected
area of each lens for image production. This provides superior
optical performance with large, level and undistorted fields of
view and chromatically optimized, high-contrast images.
ESD protection The Leica EZ5 together with its cold light source and stand is
made from highly conductive materials with area resistivity of
2×1011 Ohm/square. Charges are cut from 1000V to 100V in less
than 2 seconds.

relieve muscle tension.
The Leica EZ5 with a 60° viewing angle offers optimum viewing
height on the inclined stereomicroscope.
Interpupillary
distance, exit pupil
The interpupillary distance is adjustable in
a range from 55 – 75mm.
The exit pupil is the distance between the eye
and the eyepiece. It is
– 12mm for standard eyepieces 10×/20, 16×/16
and 20×/12, fixed and adjustable.
– 22mm for eyepieces 10×/23B and 16×/15B,
fixed and adjustable, and also for the wide-
field eyepieces for eyeglass wearers, 10×/21B,
16×/14B, 25×/9.5B and 40×/6B.
▶Move your eyes slowly towards the eyepieces
and push the tubes together or apart with two
hands until you see a single, round image field

your eyeglasses from being scratched.
Adjust working
distance,
focusing = creating
a clear image
In order to focus, the operator uses the focusing drive to raise/
lower the stereomicroscope until the desired object site is in the
focus = working distance of the objective. To see the working
distances for the various objectives, please refer to the table on
page 30.
The focusing drive can be operated with the right or left hand.
▶Place the object under the
objective.
