Introduction
Thank you for your purchase of a Motic stereomicroscope. Motic stereomicroscopes are precision
instruments, subjected to meticulous examination to reach you in perfect condition. Their design combines
easy management and optimum functioning with minimum maintenance.
The information contained in this manual is likely to go beyond what the average user needs to know to use
the stereomicroscope, however, it is provided to answer any queries that may arise.
Stereomicroscopes are used to study three dimensional objects, examine small parts, or dissect biological
specimens. They also permit the observation of slide specimens.
These instructions should be read carefully before operating the microscope. They will permit you to use
your new stereomicroscope to its fullest capabilities. Terminology used to describe components and controls
can be found in the diagram on page 2.
These instructions are based on the assembly and use of the model S-20-2LOO, with additional notes
applying specifically for the other models in the series.
Unpacking
All components of the stereomicroscope have been carefully packed to ensure they reach you in perfect
condition. We recommend that you do not discard any packing containers in case you need to return the
microscope or store it for long periods of time; or should it become necessary to transport it to a technical
service for any repair or maintenance procedure.
The box should contain the following components, depending on the model:
S-10-P: A base without illumination, a binocular vertical head with eyepiece, a plastic opaque black
and white stage, eyepiece protectors, a protective cover, and a hexagonal 2mm key.
S-10-LO: A base with incident illumination, a vertical binocular head with eyepiece, a plastic opaque
black and white stage, eyepiece protectors, a protective cover, and a hexagonal 2mm key.
S-20-LO: A base with incident illumination, an inclined binocular head with eyepiece, a plastic
opaque black and white stage, eyepiece protectors, a protective cover, and a hexagonal 2mm key.
S-20-2LOO: A base with incident, and transmitted illumination, an inclined binocular head with
eyepiece, two stages, one plastic opaque black and white stage, and a frosted glass stage, eyepiece
protectors, a protective cover, and a hexagonal 2mm key.
Avoid touching optical elements and keep clear of contact with dust, water or other contaminating
agents, as they could stain, or damage the lens surface and affect the quality of the image.
Remove, and handle all components of the stereomicroscope with extreme care.
Place the stereomicroscope upright, on a flat, stable and clean surface.
Important: before connecting the stereomicroscope to a power source, check that the voltage
coincides with that of the stereomicroscope.

Description of the components.
1. Head (4) binocular and vertical in the case of S-10 series, or inclined for the S-20 series.
2. Eyepiece (1). The collection of lenses closest to the eye, they magnify the image formed by the
objectives.
3. Objectives (5). The collection of lenses closest to the object or slide sample being examined. They
form the first image.
4. Stage (9). Flat area where the slide is placed, and help with the stage clips.
5. Focusing knob (12). Situated on both sides of the stereomicroscope head holder, they permit precise
focussing.
6. Illumination (6). Depending on the model, it incorporates a 12V and 10W incident (Base LO)
illumination system, or an incident and transmitted illumination (Base 2LOO).
Operation
A. Starting Up.
1. Changing the stage. (Only for model S-20-2LOO)
The stereomicroscope has two stages. One frosted glass for
the observation of slides, or thin, or transparent samples, such
as leaves, insect wings, etc. The other is opaque, black and
white and can be used for non-transparent samples, or for
dissection. The best contrast of a sample depends on the side
of the stage selected.

Stage support
screw
a. Loosen the stage support screw (Fig. 1) with the
key provided, and remove the stage. (9).
b. If the frosted glass stage is being used, place it so
the frosted part faces upwards.
c. Tighten the stage support screw.
Depending on model, there exist three types of light switch situated on the base of the
stereomicroscope:
MAIN : Principal switch, which turns the entire unit on or off.
I : Switch to turn incident light on or off (superior illumination)
T : Switch to turn transmitted light on or off (inferior illumination)
2. Press the principal switch (7) to on position “I”.
3. Press the incident (15) illumination switch, or the transmitted illumination switch (16) or both
to position “I” or “II”, according to necessity, for the observation of the sample.

B. Interpupillary Adjustment.
1. Whilst looking through both eyepieces (1), move eyepiece tubes (2) on their axis, holding
head by the eyepiece tubes housing the prisms. (3).
2. When a full field of view is obtained, and converted into a single image, interpupillary
distance is correct for your eyes.
3. Each user should adjust interpupillary distance to match their eyesight.
C. Focusing.
1. Place a flat object, or a specimen slide on the centre of the stage (9).
2. Turn focus knobs (12) to mid-focus range.
3. The head (4) is mounted on a column (14), and can be moved up or down to accommodate
the size of the object.
a. Support the head with one hand without touching any lens.
b. Without letting go of the head, loosen the head holding screw (11).
c. While looking through the eyepiece, move head up or down until the object
appears in focus.
d. Screw head holding screw down firmly.
e. It is not necessary to repeat these steps every time the object is changed, so long
as the objects are of similar thickness or height.
4. Adjust again focus knob until the image is completely detailed.
D. Adjusting the diopter.
On the left hand eyepiece tube there is a diopter adjustment collar. Its normal position is when the
lower part of the collar is aligned with the sign marked on the eyepiece tube.
In the case of differences in eyesight:
1. With the right eye, look through the right eyepiece (1) and adjust focus.
2. Now use the left eye to look through the left eyepiece, and adjust the focus by turning the diopter
adjuster (10), on the left hand eyepiece tube, until a detailed image is achieved. Do not adjust
the focus with the focus knobs (12).
