This microscope is a scientic precision instrument designed to last for many years with a minimum of main-
tenance. It is built to high optical and mechanical standards and to withstand daily use.
Optika reminds you that this manual contains important information on safety and maintenance, and that it
must therefore be made accessible to the instrument users.
Optika declines any responsibility deriving from instrument uses that do not comply with this ma-nual.
Safety guidelines
This manual contains important information and warnings regarding safety about installation, use and
maintenance of the microscope. Please read this manual carefully before using the equipment. To
ensure safe use, the user must read and follow all instructions in this manual. OPTIKA products are
designed for safe use in normal operating conditions. The equipment and accessories described in
the manual are manufactured and tested according to industry standards for safety instrumentation
laboratory. Misuse can cause personal injury or damage to the instrument. Keep this manual at hand
close to the instrument, for an easy consultation.
Electrical safety
Before connecting the power cord to wall outlet, ensure that your mains voltage for your region corre-
sponds to the voltage supply of the instrument, and that the illuminator’s switch is in position OFF. The
user must observe the safety regulations in force in his region. The instrument is equipped with CE sa-
fety marking, in any case the user has full responsibility concerning the safe use of that instrument.
Warning/Caution symbols used in this manual
The user should be aware of safety aspects when using the instrument. Warning or hazard symbols
are shown below. These symbols are used in this manual.

3.0 UNPACKING AND ASSEMBLY
2.0 INTRODUCTION
3.1 The microscope is housed in a moulded Styrofoam container. Remove the tape from the edge of the
container and lift the top half of the container. Take some care to avoid that the optical items (objecti-
ves and eyepieces) fall out and get damaged. Using both hands (one around the arm and one around
the base), lift the microscope from the container and put it on a stable desk.
3.2 The objectives are located in individual protective vials. Remove the objectives from the vials and
insert them into the microscope nosepiece in the order from the lowest magnication to the highest, in
a clockwise direction from the rear.
3.3 Insert the analyzer/bertrand lens block onto the top of the microscope stand and lock its screw:

3.4 Insert the observation head onto the top of the analyzer/bertrand lens block and lock its screw. If you
have a trinocular microscope and want to use the photo port, insert your adaptor in the hole on the
top of the observation head and xate it with the screw on the side:
3.5 Insert the eyepieces into the eye tubes.
3.6 Insert the condenser into its holder and lock its screw:

4.1 Adjust the observation head
Loosen the lock-screw, turn the observation head to a comfortable position for observation, and then
lock the lock-screw.
4.2 Place the specimen on the stage
Fix the specimen slide on the mechanical stage using the slide-clamp. Ensure that the specimen is
centred over the stage opening.
4.3 Lamp settings
In order to activate the transmitted light illuminator, insert the plug of the mains cable into the mains
socket and turn on the switch on the back of the main body. Turn the brightness adjustment knob to
a brightness suitable for observation.
4.4 Preliminary settings
Before trying to focus the sample, ensure that:
The eld diaphragm is fully open.
The aperture diaphragm is fully open.
No lter is inserted under the observation head.
The analyzer lter is in OUT position (lever fully pulled out).
Photo port closed (lever fully in).
Bertrand lens in OUT position (you read “0” on the Bertrand lens disc under the observation
head). Swing out lens of the condeser in OUT position (you have always to do this when observing
through 4X and 10X objective).
3.0 UNPACKING AND ASSEMBLY
4.0 USING THE MICROSCOPE
Connect the mains plug into the socket at the base
Make sure, before you turn the illumination on, that the voltage selector is set to the mains voltage for
your region.
The power cord should be used only on network sockets equipped with adequate grounding.
Contact a technician to check the state of your electrical system. If there is no need to install additional
accessories, the instrument is now ready for use. Once positioned and installed with the necessary
components, the microscope is ready to be used. Your microscope is a laboratory instrument desi-
gned to last. Handle it always carefully and avoid abrupt vibrations or shocks. Always disconnect the
power cable from the microscope when not in use for long time, while you clean it or when you perform
any maintenance.
AVOID DISASSEMBLING THE INSTRUMENT
Do not disassemble the instrument. This entails the cancellation of the warranty and may cause
malfunction.

4.5 Adjust interpupillary distance
Hold the right and left parts of the observation head using both hands and adjust the interpupillary
distance by turning the two parts until one circle of light can be seen.
4.6 Focus and diopter adjustment
Loosen the focus-stop knob, rotate the coarse focusing knob to bring the slide into focus with a 4X
or 10X objective, then lock the focus-stop knob. Adjust the ne focusing knob to get the image sharp
and clear while observing with your right eye, then turn the left diopter ring to a sharp and clear
image also with the other eye. Turn the tension-adjust-knob to get a suitable tension for the focus
system.
4.7 Align the system
Insert the swing out lens of the condenser and fully close the eld diaphragm. Rotate the condenser
adjustment knob until you see a sharp image of the closed eld diaphragm (a bright spot of light).
Act on the condenser centering screws until you move the bright spot in the center of the image
eld. Then re-open the eld diaphragm.
4.8 Center the stage
With the Bertrand lens out, focus on your slide. Center the optical axis of the objective you are using
with the rotation axis of the stage using the two centring screws above each objective.
A fairly easy method of centring is the following: look at your sample while continuously rotating the
stage clockwise and then counter-clockwise by a little angle (e.g. 30° or 45°). During these oscilla-
tions you should spot a point on the sample that doesn’t rotate on a circumference but only revol-
ving about itself. With the two objective’s centering screws, bring this point in the center of the eld
of view. In this way the mechanical center of rotation of the stage coincides with the system’s optical
axis. The stage can be locked in its position using the stage lock knob.

4.9 Set the numerical aperture
Adjust the aperture of the iris diaphragm under the condenser to set the numerical aperture of the
illuminator, thus controlling image contrast and resolution.
4.10 Bertrand lens
In order to have a conoscopic view of your sample, you can insert a Bertrand lens in the optical path
by rotating the disc under the observation head.
The Bertrand lens can be ne aligned along Z axis by rotating this disc:
The lens can also be centered in X-Y axis by means of two screws located at the back of the lens:
