The OPTIkA zoom stereo microscopes SZM-gEM series are high performance greenough micro-
scopes with continuous zoom system 0.7:4.5.
These instruments are made for examining any three dimensional object in industrial, biological and
educational applications, and especially for gemmological use. They are equipped with two separa-
te optical systems that give an excellent field depth to the image, a stereoscopic effect.
The advanced illumination system, using a combination of halogen incident light and LED brightfield/
darkfield transmitted light, allows a thorough and complete analysis of the surface of the object.
There are, at the moment, 2 models in the series:
SZM-1-GeM
: binocular head. Simple stand for incident light with focusing controlled by a pair of
knobs. base size: 29x23 cm; stand height: 22 cm.
SZM-2-GeM:
Trinocular version of model SZM-1-gEM. Suitable for photo/video applications.
The components for the SZM 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.
unpack the stand and put it on a good stable table. Loosen the lock screw of the focusing carrier,
adjust the height of the focusing carrier and lock the lock screw again.
Put the stereo head onto the focusing carrier and lock it by the lock screw on the side of the focu-
sing 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. when handling the optical parts, avoid touching any lens surface with naked hand or fingers.
Any fingerprints or grease stains will negatively affect the image quality.
If you’re planning to use the sample clip for gemstone inspection, unpack it and screw it on the ap-
propriate hole in the stand near the illuminator.
