Leica StereoZoom User Manual
Workplaces with stereomicroscopes facilitate and improve the
viewing task, but they also impose high demands on the eyes
and holding muscles of the user. Dependent upon the duration
of uninterrupted activity, this may lead to asthenic trouble and
muscular-skeletal pain so that suitable measures must be taken
to reduce the strain:
– perfect design of workplace, work content and work process
(frequently changing activities).
– detailed introduction of the personnel while considering
ergonomic and organizational work-related aspects.
The ergonomic optics concept and the design of the
Leica S series aim at limiting the strain on the user to the
lowest possible level.
Direct contact with eyepieces can be a potential transmission
path for bacterial and viral infections of the eye. Users should
be made aware of the potential risk of infection. The risk can be
kept at a minimum by using individual eyepieces or attachable
eyecups (see p. 17).
Electrically operated equipment
Handle liquids carefully.
Liquids spilt on the instrument
– can cause the stereomicroscope and other equipment to
become electrically live and injure persons,
– can cause damage to the instrument.
Check regularly to ensure that the mains cable is
undamaged and avoid jerking or pulling the cable hard.
Faulty mains cables
• can injure persons,
• can cause the stereomicroscope and other equipment to
become electrically live and injure persons.
Ensure the cable is not in a position where someone could
accidentally catch it, otherwise the instrument could tip
over and fall, damaging itself or other equipment, or injuring
people nearby.
Electrical equipment may only be repaired by authorized
Leica personnel.
Disconnect the mains cable before opening the instrument.
Touching the open instrument when voltage is
applied may result in injury.

connected to the transformers. Overloading can result
in damage to the instrument.
• Disconnect the mains cable from the mains supply before
changing lamps.
• Never put your hand in the lamp housing or transmittedlight stand when the instrument is connected to the mains.
• Wait for filament lamps to cool down before
changing. Touching hot filament lamps can result
in burns.
Observe all statutory accident prevention and environmental
protection requirements.
National laws and regulations must be observed for the disposal of these products.
Electrically operated accessories for Leica S4 E, S6 E, S6, S6 T,

The optical system of the Leica StereoZoom®line consists of two beam paths converging at 12°. Since the
pairs of objectives are very close together, the stereomicroscopes can be constructed very “slim” towards
the base. This has a number of advantages: less space
required for use on bonders and machines, unimpeded
working on the object, plenty of room for tools, free view
of the object field.
The Greenough system provides a low-cost solution for
correcting aberrations such as chromatism, curvature of
the field of view and distortion. On the new Leica StereoZoom®line the optimally corrected centre of the objective is used for the image. This results in excellent
optical performance with large, flat, distortion-free fields
of vision and high-contrast images with maximum
chromatic correction.
The Leica S4 E, S6 E, S6, S6 D and S8 APO stereomicroscopes including cold-light source and stand are made of
antistatic material with a surface resistance of 2×10
11
ohm/square and a discharge time from 1000V to 100V of
under 2 seconds.
The Leica S6 T Terminator for problematical work areas
and the T incident-light stand are made of antistatic material with a surface resistance of 102–106ohm/square
and a discharge time from 1000V to zero of under
0.1 seconds.
The Leica StereoZoom®S6 D and S8 APO models are
equipped with a built-in video/photo tube that allows for
simple, quick setting up of digital, film and analog video
cameras.

World first Leica StereoZoom®S8 APO is the first stereomicroscope
on the market with completely apochromatic corrected
Greenough system. Apochromatic optics corrects perfectly chromatic aberrations, eliminates interfering color
fringes and renders even the finest details ultra sharp.
Contrast, brilliance, sharpness, resolution, color fidelity
and reproduction accuracy are unsurpassed. The advantage of apochromatic correction is best observed in
objects that have fine, low-contrast structures such as
large animal cells, cilia plants or metallic microelectronic
structures.

You wear spectacles for your
work.
왘 Fold the eyecups downwards.
• The folded-down eyecups will
protect your spectacle lenses
against scratching.
To focus the stereomicroscope, raise or lower it using the
focusing drive until the desired object segment is in
focus, i.e. inside the objective’s working distance. The
working distances of the various objectives are listed in
the tables on pages 38–40.
You can operate the focusing drive with either your right
or left hand.
왘 Position the object under
the objective.
왘 Select the minimum
magnification.
• You should select the minimum
magnification because it is
easier to find the desired
object segment in a large field
of vision.
왘 Look into the eyepieces.
왘 Focus the object by turning the pinion knob.

Is the focusing drive too stiff/too loose or does the set-up
slip down unassisted? You can tension the focusing drive
to suit the weight of the set-up and your own needs:
왘 Take one pinion knob in each hand and turn in
opposing directions until the desired tension is
reached.
The optics carrier can be tilted
sideways if the user wants to
work from a lateral position:
왘 Loosen the clamping bolt.
왘 Tilt the optic carrier side-
ways to the desired position.
왘 Tighten the clamping bolt.

models are equipped with a continuously
adjustable magnification changer that can be operated
with either the right or left hand. The right-hand pinion
knob carries a magnification scale. The ranges are:
– 0.63 to 3 on the S4 E and
– 0.63 to 4 on the S6 models
– for S8 APO from 1 to 8
The tables on pages 38 to 40 list the magnifications and
field diameters as a function of magnification changer
position and the eyepiece/objective combination being
used.

Preparations
Bring the test
object into focus
If you adjust the diopters at the adjustable eyepiece as
described below, the focus will remain constant, or parfocal, from minimum to maximum magnification. In other
words, you will not have to refocus when you change
magnification, but only when you want to examine a
higher- or lower-positioned object segment. Make full
use of this feature, which is not available on every stereo
microscope.
• Diopter adjustment is possible within a range
from +5 to –5.
Every user has to make the following adjustments
only once.
If you are using a graticule, the diopter adjustment and
parfocality setting procedure is slightly different to that
described here. Please refer to the section on measurement in the graticule user manuals.
Setting up diopter with an adjustable and a fixed
eyepiece
왘 Set up illuminator.
왘 Set interpupillary distance (p.23).
왘 Set approximate working distance using the focusing
drive (see p.38–40 for the working distances of the
various objectives).
왘 Position a flat test object
beneath the objective.
왘 Set the microscope to
