2.0 INTRODUCTION
The OPTIKA stereozoom head SZN is an high performance Greenough microscope with continuous
zoom system 0.67x - 4.5x, and widefield high-point 22mm eyepieces.
These instruments are made for examining any three dimensional object in industrial, biological and
educational applications. They are equipped with two separate optical systems that give an excellent
field depth to the image, a stereoscopic effect.
There are, at the moment, 2 models in the series:
SZN-B: Binocular head.
SZN-T: Trinocular version.
Suitable for photo/video applications.
3.0 UNPACKING AND ASSEMBLY
The components for the SZN series are shipped in a Styrofoam box for protection. Open the box with
care to avoid that any components fall out and get damaged.
If the instrument has been damaged during the transport, please contact both the carrier and your
supplier immediately.
Put the stereo head onto the focusing carrier of the stand (sold separately) and lock it by the lock
screw on the side of the focusing carrier. During the operation of the microscope, this screw should
always be locked to maintain maximum stability.
Unpack the eyepieces and other optical parts carefully and place the eyepieces into the eyepiece
tubes. Make sure that the eyecups are placed on each eyepiece, for a more comfortable view.
When handling the optical parts, avoid touching any lens surface with naked hand or fingers. Any
fingerprint or grease stains will negatively affect the image quality.

4.0 USING THE MICROSCOPE
4.1 Adjust interpupillary distance
Hold the right and left eyepiece tube with both hands
and adjust the interpupillary distance by moving 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.
4.2 Focus
Put the sample to be observed on the plate and turn
the zoom to the highest magnification using the bilateral zoom knob. Try to focus the sample using
the focusing knobs of the stand.
If necessary adjust the height of the microscope head along the vertical stand. Remember to lock
the lock screw and support collar after aligning the height of the microscope.
4.3 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 magnification. 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
magnification).
4.4 Magnification and working distance
The total magnification varies depending on the eyepieces and auxiliary objectives used. With the
bilateral zoom knob, the user can change the magnification in a factor of 6.72 with perfect parfocality
and the image is always centred.
Select the desired magnification by adjusting the bilateral zoom knob. Change the eyepieces and/or
add an appropriate magnifying objective lens if necessary. The total magnification used can be cal-
culated by the following equation:
Total magnification = Eyepiece magnification x Zoom magnification x Objective lens magnification
Normal working distance for the standard configuration (1x objective lens) is 100 mm.

4.5 Video capturing (optional)
Two kinds of observation heads, binocular or trinocular, are available for the SZN series. They can
all be connected to cameras via an adaptor, for digital and analogical photo and video capturing.
Before taking a picture or filming video, pull out the light path selector lever so the light will be de-
flected into the photo tube. At the same time, no light will enter into the right eyepiece tube for obser-
vation. Please refer to the adaptor and camera manuals for further details.
5.0 MAINTENANCE
4.0 USING THE MICROSCOPE
5.1 Microscopy environment
This microscope is recommended to be used in a clean, dry and shock free environment with
a temperature of 0-40°C and a maximum relative humidity of 85 % (non condensing). Use a
dehumidifier if needed.
5.2 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 off the light immediately, cover the microscope with the included dust-cover,
and keep it in a dry and clean place.
5.3 Cleaning the optics
• If the optical parts need to be cleaned try first to: use compressed air.
• If that is not sufficient: use a soft lint-free piece of cloth with water and a mild detergent.
• And as a final option: use the piece of cloth moistened with a 3:7 mixture of ethanol and
ether.
Note: ethanol and ether are highly flammable 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.

7.0 OPTIONAL ACCESSORIES
7.1 Eyepieces and auxiliary objectives
With the standard equipment is included a pair of 10x eyepieces. There are also 15x and 20x
eyepieces available as optional accessories.
To change the eyepieces, remove the original eyepieces and replace with the new pair.
The standard objective is 1x, and other magnifications are available. An additional objective
can be needed to obtain a specific magnification or a different working distance.
The additional objective is mounted simply by screwing it onto the stereo-head. The height
of the microscope has to be re-adjusted as the working distance is changed when additional
objective is used.
