Unpacking
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 (objectives 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.
Using the microscope

1. Place the specimen on the stage
Place the specimen on the microscope
stage and lock the specimen using the
slide-clamp if it is necessary. Ensure that
the specimen is centred over the stage
opening. (Fig.1)
2. Turn on the light
The microscope comes with an electrical
illuminator. Insert the plug of the cable into
the power socket, turn on the switch on the
main body and select your light source.
(Fig.2)
3. Adjust interpupillary distance
Hold the right and left parts of the
observation head by both hands and
adjust the interpupillary distance by
turning the two parts until one circle of
light can be seen. If two circles appear,
the interpupillary distance is too big, and
if two overlapped circles appear, the
interpupillary distance is too small. (Fig.3)
4. Focus
Rotate the focusing knob to bring the
sample into focus with the highest
magnification. (Fig.4)

5. Dioptric compensation
This compensation makes it possible
for people with glasses to adjust the
microscope to their eyes and use the
microscope without glasses. Adjust the
diopter compensation ring of the right
eyepiece tube until the image of the right
eyepiece is clear and sharp. Repeat the
procedure for the left eyepiece. (Fig.5)

Maintenance
Microscopy environment
This microscope is recommended to be used in a clean, dry and shock free environment with a temperature of
5°-40°C and a maximum relative humidity of 75 % (non condensing). Use a dehumidier if needed.
To think about when and after using the microscope
• The microscope should always be kept vertically when moving it and be careful so that no
moving parts, such as the eyepieces, fall out.
• Never mishandle or impose unnecessary force on the microscope.
• Never attempt to service the microscope yourself.
• After use, turn o󰀨 the light immediately, cover the microscope with the included
dust-cover, and keep it in a dry and clean place.
Electrical safety precautions
• Before plugging in the power supply, make sure that the supplying voltage of your region
matches with the operation voltage of the equipment and that the lamp switch is in o󰀨-
position.
• Users should observe all safety regulations of the region. The equipment has acquired
the CE safety label. However, users do have full responsibility to use this equipment safely.
Cleaning the optics
• If the optical parts need to be cleaned try rst to: use compressed air.
• If that is not su󰀩cient: use a soft lint-free piece of cloth with water and a mild detergent.
• And as a nal option: use the piece of cloth moistened with a 3:7 mixture of ethanol and ether.
Note: ethanol and ether are highly ammable liquids. Do not use them near a heat source, near sparks or
near electric equipment. Use these chemicals in a well ventilated room.
• Remember to never wipe the surface of any optical items with your hands. Fingerprints can damage the
optics.
• Do not disassemble objectives or eyepieces in attempt to clean them.
For the best results, use the OPTIKA cleaning kit (see catalogue).
If you need to send the microscope to Optika for maintenance, please use the original packaging.
