nance. It is built to high optical and mechanical standards and to withstand daily use. We remind you that this
manual contains important information on safety and maintenance, and that it must therefore be made acces-
sible to the instrument users. We decline any responsibility deriving from incorrect instrument use uses that does
not comply with this manual.
Symbols and conventions
The following chart is an illustrated glossary of the symbols that are used in this manual.
CAUTION
This symbol indicates a potential risk and alerts you to proceed with caution.
ELECTRICAL SHOCK
This symbol indicates a risk of electrical shock.
Safety Information
Avoiding Electrical Shock
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 have full responsibil-
ity to use this equipment safely. Please follow the guidelines below, and read this manual in its entirety to ensure
safe operation of the unit.
Intended use
For research and teaching use only. Not intended for any animal or human therapeutic or diagnostic use.

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.
Assembling
Once you open the box, these are the microscope’s components:
① Stereo Head
② Microscope stand
③ Eyepieces
④ Black/white
contrast disc
⑤ Power cable
③④

1. Insert the stereo head into the holder on
the stand, and tighten the side screw.
(Fig.1)
2. Insert the eyepieces into the tubes of the
head. (Fig.2)

Fig.5Fig.4
Fig.6
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.3)
2. Turn on the light
The microscope comes with an electrical
illuminator. Insert the plug of the cable into
the power socket and turn on the switch on
the main body and select your light source.
(Fig.4) Turn the light intensity control to a
brightness suitable for observation. (Fig.5)
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.6)
4. Focus
Rotate the focusing knob to bring the
sample into focus with the highest
magnication. (Fig.7)
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. Turn the
zoom down to the lowest magnication.
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. Then,
check the focus of the image for the whole
zoom range. It should now be perfectly
parfocal (focus is always maintained during
the change of magnication). (Fig.8)
Using the microscope

6. Magnication
Select the desired magnication by
adjusting the zoom knob. Change the
eyepieces and/or add an appropriate
magnifying objective lens if necessary.
(Fig.9)
Total magnication used can be calculated
as:
Eyepiece magnication x Zoom
magnication x Objective lens
magnication.
7. Contrast disc
You can use the black/white disc in order
to enhance the contrast of the image when
using the incident illumination. (Fig.10).
If you want to look at bright opaque
objects, place the disc with the black side
up. (Fig.11)
8. Working distance
Normal working distance for the standard
conguration is 80 mm (LAB-10) and
85mm (LAB-20 & LAB-30). (Fig.12)
9. Video capturing
Two kinds of observation heads, binocular
or trinocular, are available for the LAB
series. They can all be connected to
cameras via an adaptor.
Please refer to the adaptor and camera
manuals for further details.

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 dehumidier 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 sucient: 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.

Troubleshooting
Review the information in the table below to troubleshoot operating problems.
PROBLEM CAUSE SOLUTION
I. Optical Section:
The illumination is ON, but the eld of
view is dark.
The plug is not connected to the il-
lumination
Connect the cable
The brightness is too low Adjust to a proper setting
The edge of the eld of view is
vignetted or the brightness is
asymmetric.
The incident illuminator is not cor-
rectly oriented
Change the angle of the incident illuminator
Dust and stains can be seen in the
eld of view.
There are stains and dust on the
specimen
Clean the specimen
There are stains and dust on the
eyepiece
Clean the eyepiece
Poor image quality:
The image is not sharp
The contrast is not high
The details are not clear
The lenses (condenser, objective,
eyepieces is dirty
Thoroughly clean all the optical system
One side of the image is out of focus. The specimen is out of place (tilted) Place the specimen at on the stage.
II. Mechanical Section:
The coarse focus knob is hard to
turn.
The tension adjustment collar is too
tight
Loosen the tension adjustment collar
The focus is unstable. The tension adjustment collar is too
loose
Tighten the tension adjustment collar
III. Electric section:
The LED doesn’t turn on. No power supply Check the power cord connection
The brightness is not enough The brightness adjustment is low Adjust the brightness
The light blinks The power cord is poorly connected Check the power cord
IV. Viewing tube assembly:
The eld of view of the two eyes is
dierent
The interpupillar distance is not cor-
rect
Adjust the interpupillar distance
The dioptric correction is not right Adjust the dioptric correction
The viewing technique is not cor-
rect, and the operator is straining the
eyesight
When look into the objective, do not stare
at the specimen but look at the whole eld
of view. Periodically, move the eyes away
to look at a distant object, then back into
the objective
V. Microphotography and video:
The image is unfocused Incorrect focussing Adjusting the focus system as in the
present manual
The edge of the image is unfocussed To some degree, it is inherent to the
nature of achromatic objectives
The problem can be minimized by a correct
setting of the aperture diaphragm
Bright patches appear on the image Stray light is entering the microscope
through the eyepieces and through
the camera viewnder
Cover the eyepieces and the viewnder
with a dark cloth
