6. 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 opti-
cal 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.
Do not touch with bare hands optical surfaces such as lenses, lters or glasses. Traces of grease or
other residuals may deteriorate the nal image quality and corrode the optics surface in a short time.

7.4 Assembling the microscope
The microscope comes already assembled from the
factory. No assembling procedure is requested.
1. Open the battery compartment placed in the lo-
wer part of the frame. (Fig. 1)
2. Insert batteries, respecting polarity.
3. Close the battery compartment.
4. Plug the jack of the power supply into the socket
① in the back side of the microscope. (Fig. 2)
7.5 Polarizing set (optional)
1. Place the polarizer on the light exit lens ②at the
base of the microscope. (Fig. 3)
2. Using a at screwdriver (not provided) loosen the
xing screws on the two sides of the microscope

8. Use of the microscope
8.1 Switching the microscope
Operate on the light intensity adjustment dial ① to
turn ON / OFF the microscope. (Fig. 6)
8.2 Light intensity adjustment
Operate on the light intensity adjustment dial ①to
increase / decrease the illumination voltage. (Fig. 3)
8.3 Stage
B-61
1. Raise the xing clips and place the slide on the
stage.
2. Lower the clips to hold the slide and prevent
accidental falling. (Fig. 7)
B-62 / B-63 / B-65 / B-66 / B-67 / B-69
Stage accepts standard slides 26 x 76 mm,
thickness 1,2 mm with coverslide 0,17mm. (Fig. 8)
1. Open the spring arm of the slide holder ② and
place the slide from the front on the stage.
2. Gently release the spring arm of the slide holder.
• A sudden release of the spring arm could
cause the falling of the slide.
8.4 Adjust the interpupillary distance
B-66 / B-67 / B-69
Hold the right and left parts of the observation head
using both hands and adjust the interpupillary distan-
ce by turning the two parts until one circle of light can
be seen. (Fig. 9)
• The graduation on the interpupillary distance in-
dicator ③, pointed by the spot “.” on the eyepiece
holder, shows the distance between the opera-
tor’s eyes.
The range of the interpupillary distance is 55-75 mm.
Fig. 9

Page 11
8.5 Diopter adjustment
B-66 / B-67 / B-69
1. Look into the right eyepiece with your right eye
only, and focus on the specimen.
2. Look into the left eyepiece with your left eye
only. If the image is not sharp, use the dioptric
adjustment ring ① to compensate. (Fig. 10)
• The adjustment range is ±5 diopter. The num-
ber indicated on the adjustment ring gradua-
tion should correspond to the operator’s dio-
ptric correction.
8.6 Use of oil immersion objective
B-65 / B-69
1. Focus the specimen with a low power objective.
2. Lower the stage.
3. Put a drop of oil (provided) on the area of the
specimen to be observed. (Fig. 11)
• Make sure that there are no oil bubbles. Air
bubbles in the oil damage the image quality.
• To check for bubbles: remove an eyepiece, ful-
ly open the aperture diaphragm and observe the
objective exit pupil. (The pupil must be circular
and bright).
• To remove the bubbles, gently move the nose-
piece to the right and left to move the immersion
objective a few times and allow the air bubbles
to move.
4. Insert immersion objective.
5. Return the stage to the upper focusing point and
obtain an optimal focus using the ne focus knob.
6. After use, gently remove the oil with a soft paper
towel or a lightly moistened optic paper with a
mixture of ethyl ether (70%) and absolute ethyl
alcohol (30%).
• The immersion oil, if not immediately cleaned,
could crystallize creating a glass-like layer.
In this situation the observation of the speci-
menwouldbedi󰀩cult(evennotimpossible)
due to the presence of an additional thickness
on the objective.

8.7 Aperture diaphragm
The Numerical Aperture (N.A.) value of the aper-
ture diaphragm a󰀨ects the image contrast. Incre-
asing or reducing this value one can vary reso-
lution, contrast and depth of focus of the image.
Move the diaphragm lever ① (Fig. 12) toward left
or right to decrease or increase the N.A. value.
• With low contrast specimens set the numerical
aperture to about 70%-80% of the objective’s N.A.
If necessary, remove on eyepiece and, looking into
empty sleeve, adjust the condenser’s diaphragm
in order to obtain an image like the one in Fig. 13.
8.8 Use with rechargeable batteries
When the microscope is connected to the power sup-
ply the batteries are recharged normally.
When the microscope is disconnected from the po-
wer supply, the batteries start operating by powering
the microscope.
8.9 Battery replacement
1. Open the battery compartment placed in the lo-
wer part of the frame. (Fig. 14)
2. Replace batteries, respecting polarity.
3. Close the battery compartment.
8.10 Use of the locking screw
The locking screw prevents the stage from rising
above a certain limit avoiding contact between the
objective and the slide, so as not to damage the lens
and do not break the slide.
The screw is preset at the factory, but to adjust the
position according to your preferences, act like this:
1. Insert the highest magnication objective and fo-
cus the specimen.
2. Unscrew the locking screw ② and raise the sta-
ge until the objective is almost in contact with the
slide. (Fig. 15)
3. Lock the locking screw. Fig. 15
②
Fig. 14

8.11 Use of the polarizer (optional)
1. Remove the specimen from the stage.
2. Looking inside the eyepieces, rotate the polarizer
until the darkest position is achieved.
3. Once the dark is achieved (“extinction” or “Cros-
sed Nicol” position) it is possible to begin the
observation.
8.12 Use of the mirror (only B-61)
1. Unscrew the lens ① from the frame. (Fig. 16)
2. Insert the base of the mirror ② in the empty hole
in the frame. (Fig. 17)
3. Rotate or tilt the mirror surface toward the light
in order to achieve a proper illumination of the
specimen.
• Due to the condenser dimension, the mirror
can be used only on B-61 model. It is not pos-
sible the use with any other model.

9. Maintenance
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 provided 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.
