9. Using the microscope
9.1 Adjusting interpupillary distance
1. Hold the right and left eyepiece tube with both hands and ad-
just the interpupillary distance by moving the two parts until
one circle of light can be seen. (Fig. 6)
• If two circles appear, the interpupillary distance is too big.
• If two overlapped circles appear, the interpupillary distance
is too small.
③④
9.2 Diopter compensation
• This compensation makes possible for people wearing
glasses to adjust the microscope to their eyes and use
the microscope without glasses.
1. Put the zoom down to the lowest magnication ① and focus
the specimen with the focusing knobs ②. (Fig. 7)
2. Put the zoom to the maximum magnication and repeat the
focusing.
3. Return to the lowest magnication: the specimen will be out
of focus.
4. Adjust the diopter compensation ring of the right eyepiece
③ (Fig. 8) until the image of the right eyepiece is clear and
sharp. Repeat the procedure for the left eyepiece ④.
5. Check the focus of the image for the whole zoom range. It
should be perfectly parfocal (focus is maintained during the
change of magnication).

Page 11
9.3 Magnication
1. Select the desired magnication by adjusting the zoom knob
①. (Fig. 9)
• Change the eyepieces if a di󰀨erent magnication range is
needed.
• The microscope body is equipped with a “click-stop”
function that allows to obtain a precise setting of the desired
magnication.
• Total magnication used can be calculated as:
Eyepiece magnication * Zoom magnication * Objective lens
magnication.
Eyepiece 10x
Field number (mm) 24
Objective Total Mag F.O.V (mm)
1X 7.5X - 135X 30.67 - 1.7

9.4 Use of aperture diaphragm
By varying the diaphragm aperture, the user can adjust the image
to achieve better contrast and greater depth of eld. (Fig. 10)
1. Move the aperture diaphragm lever ② to the right or left.
Rotation towards “ ” opens the diaphragm while rotation
towards “ ” closes it.
2. Adjust the diaphragm during observation to optimize the
e󰀨ect on contrast and depth of eld.
• Do not close the diaphragm too tightly so as not to have
a poor image quality and not to have an excessively dark
image.
9.5 Use of trinocular port
Observation head is equipped with a light split selector ③.(Fig.
11)
1. Moving the selector to the “eye” position ④ allows the
binocular observation.
2. Moving the selector to the “camera” position ⑤ allows the
trinocular observation.
• When the selector is in the “camera” position the right
eyepiece will be completely dark. This is not a defect.

Page 12
9.6 Use of transmitted light illumination
1. Set the main switch ① to “I” to turn on the base. (Fig. 12)
2. Turn the light intensity adjustment knob ② to adjust the
brightness to the sample under observation.

②
3. Move the lever ③ located on the right side of the base. (Fig.
13)
• This lever controls a black foil which slides horizontally along
the light exit.
• Using the OIC (Oblique Illumination Contrast) system allows
you to modulate the light to obtain three di󰀨erent types of
observation.
4. When the foil is outside the optical path (Fig. 14), brighteld
(BF) observation is obtained.
5. When the foil is completely inside the optical path (Fig. 15),
dark eld (DF) observation is obtained.

①
6. Moving the foil to an intermediate position (Fig. 16) results in
the modulation of light called Oblique Illumination (OIC).
9.7 Use of conversion lens
• The conversion lens is used to optimize the light intensity
according to the objective in use. (Fig. 17)
1. Fully insert the lever ① when using 1.6x or 2x objectives.
2. Pull lever ① all the way out when using 0.5x or 1x objectives.
• There are currently no additional objectives available
other than the standard 1X objective.

10. Microphotography
10.1 Installing the camera
1. Screw the camera on the provided C-mount adapter.
2. To obtain a perfect alignment of the camera with respect to
the eyepieces, loosen the xing screw ① on the C-mount
adapter, rotate the camera until correct alignment is achieved,
then tighten the screw. (Fig. 18)
①
10.2 Parfocality adjustment
In order to have the same focus when observing the specimen
through the eyepieces and on the screen/monitor, please check
that the microscope is properly installed and follow the instruc-
tions below.
1. Use a low power magnication and focus the specimen.
2. Reach the highest magnication available using the zoom
knob and then focus the specimen again.
3. Turn on the live-view on the camera, without changing the
focus on the microscope.
4. While observing the image on the screen/monitor, adjust the
focus by turning the knurled knob ② on the C-mount adapt-
er. (Fig. 19) FFig. 19ig. 19

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
