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 functionality 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 objects, 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 SMZ-168 model with additional notes
specifically for the other models in the series.

Unpacking
All components of the stereomicroscope have been carefully packed to make sure they reach you
in perfect condition. We recommend that you do not discard any of the 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 provider for any repair, or maintenance.
The box should contain the following components:
 SMZ-168 (Binocular) :
An illuminated base with a pole for a moveable head with illumination. A black and white
opaque stage, a binocular head with eyepieces, eyepiece protectors, a frosted glass stage, a blue
filter, a protective cover and a 1.5mm hexagonal key.
 SMZ-168 (Trinocular) :
An illuminated base with a pole for a moveable head with illumination. A black and white
opaque stage, a trinocular head with eyepieces, eyepiece protectors, a frosted glass stage, a
blue filter, a protective cover and a 1.5mm hexagonal key.
Remove and handle all components of the microscope with extreme care.
Avoid touching the lenses of the optical elements and keep them clear of dust, water or other
contaminating agents as they could stain or damage the lens surface affecting the quality of
the image.

Assembly
All the steps described for the assembly of the stereomicroscope must be undertaken with
extreme care and without forcing the placement of the distinct parts and elements of the
stereomicroscope.
A. Place the base of the microscope (11) upright on a flat, stable and clean surface.
B. Loosen the head holder locking screw (5) and place the head (13) in the head holder (15) with
extreme care.
C. Tighten the head holder locking screw (5).
D. Connect the incident illumination to the power cord (12) located at the upper part of the column (18).
Warning: Before connecting the stereomicroscope to a power source, always check that
the output voltage coincides with that of the stereomicroscope.

Operation
A. Starting Up
The stereomicroscope has two stages. One is a frosted glass stage and is used for the
observation of microscope slides or samples that are thin or transparent, such as leaves, insect
wings, etc. The black and white stage is used for non-transparent objects or for dissection. For
the best contrast, choose the side of the stage best suited for your specimen.
Warning: Transmitted illumination can ONLY be used with the frosted glass stage. The
heat generated by the transmitted illumination can melt or damage the black and white
stage. Such damage would not be covered under warrantee.
1. Changing the stage.
a. Using your fingers, remove the stage (10).
b. To use the glass stage, insert the blue filter into the centre of the filter receptacle with the
frosted surface facing down.
c. Replace the glass stage.
2. Before connecting the stereomicroscope to a power source, adjust the light intensity to its
minimum (22). This must be repeated every time the stereomicroscope is turned on or off to
prolong the life of the bulb.
Three light switches are located on the base of the microscope.
MAIN : The principal switch, which turns the whole unit on or off.
I : Turns incident light on or off (illumination from above).
T : Turns transmitted illumination on or off (illumination from below).
3. Turn the principal switch (19) to the ON position.

4. Turn on the incident illumination (20) or transmitted illumination (21) or both at the same
time (“I” and “II”) according to the sample being observed.
5. Light intensity should be adjusted according to the objective used or the type of sample being
observed.
6. The angle of incident illumination can be adjusted by using the adjustment screw (8) which
can be used to vary the orientation of the lens.
B. Interpupillary adjustment
1. Looking through the eyepieces (1), move the eyepiece tubes (3) by taking hold of the prism
housing (4) and moving it outwards or inwards.
2. Interpupillary distance is correct when the two fields of view observed through both
eyepieces appear as one complete field of view.
3. Interpupillary distance should be adjusted for each new user.
C. Focusing
1. Turn the zoom knob (14) to the lowest magnification, 0.75X.
2. Place a flat object or a microscope slide on the centre of the stage (10).
3. Turn the focusing knobs (16) to mid-focus range.
4. The head holder (15) is mounted on a column (18) on which it can be moved up or down
depending on the size of the object to be focused on.
a. Support the head holder (15) with one hand without touching any lenses and with the
other loosen the screw on the support collar (17). The head holder can then be slid to the
base (11).
b. Without letting go of the head, loosen the head holder locking screw. (Fig.1)

Fig.1
c. While looking through the eyepieces, move the head holder up or down until the object
appears in focus.
d. Tighten the head holder locking screw. Do not let go of the head yet.
e. Slide the security collar up to the head holder and tighten the support collar screw. The
head can then be released.
f. It is not necessary to adjust the head every time the sample is changed, only when unable
to bring the image into focus.
5. Adjust the focus knobs (16) until the image appears sharp.
8

D. Diopter adjustment
Diopter adjustment collars are located on the eyepiece tubes. They are in normal position when
the lower part of the collar is aligned with the sign marked on the eyepiece tube.
To compensate for differences in eyesight:
1. Using only the right eye, look through the right eyepiece (1) and adjust the focus.
2. Next, using the left eye, look through the eyepiece and adjust the focus by turning the diopter
adjuster (2) located on the left-hand tube (3) until the image appears sharp. Do not use the
focus knobs to adjust focus (16).
E. Changing magnification
1. Turn the zoom control (14) to the lowest magnification and bring the image into focus.
Immediately switch to the highest magnification and do the same.
2. The stereomicroscope is now parfocal. However, some minor focus adjustments may have
to be made when switching from a higher strength objective to a lower strength objective.
Switching from a lower strength to higher strength objective should require no focus
adjustment.
Attaching a photographic or video camera (Only for SMZ-168TL)
The SMZ-168 TL model comes equipped with a vertical image port on the head for the
installation of a photographic reflex type camera or video camera, using the corresponding
adapters.
At the back of the head there is a selection lever that transmits the image to the vertical port. When
the lever is opened, the image is transmitted to the vertical port but cannot be seen through the
right eyepiece.
