Product description

More about the series SZO...

SZO Series

OPTIKA SZO Series represents a very compact Greenough stereo microscope with 6.72:1 zoom and 110mm working distance for professional environments and laboratories which allows the observation of samples without any particular preparation, yet producing incredibly crisp and detailed images. An extensive range composed by binocular and trinocular heads with 23mm field of view for a very wide peripheral view and comfortable posture even after several hours of operation. Trinocular heads enable simultaneous eyepiece and camera observation, opening new horizons and enabling a very practical and comfortable operation. Discover how easily an enhanced accuracy and repeatability can be achieved thanks to the click-stop zoom for precise and repetitive observations. An extremely wide stand selection gives the chance to create tailored stereomicroscope: choose among the several models available to cover every customers’ needs, in terms of illumination (including the state-of-the-art, exclusive X-LED³ incident light of 3.6W on selected models), arm extension (including overhanging stands) and focusing system. Special external illuminators and moving/heating stages are also available for specific applications. Keep in my mind the application, always: if you are soldering a printed circuit board, it may be more important to have a long working distance; if you are counting items, then a large field of view will be of great assistance.

Greenough Optical System

The V-shape optical path of Greenough allows us to design a very compact and a slim unit,highly versatile and appreciated for the 3D viewing. Samples with significant depth can be quickly inspected. Binocular and trinocular heads are 45° inclined to grant comfortable posture to the user even after several hours of operation.

Reliable crisp images, repetable zoom settings

Discover how easy is to obtain precise reproduction of magnifications, thus simplifying inspections and measurements. Now, with SZO your observations are easier thanks to the 11-step click-stop system in the zoom which allows you to exactly set the magnification at the same level of the previous time. Zoom control is greatly facilitated with no need of constantly look at the magnification knob.

Incredibly practical and comfortable, especially with cameras

Trinocular heads enable simultaneous eyepiece and camera observation, opening new horizons and enabling a very practical and comfortable operation. Watch at the same time your specimen on a monitor and directly in the eyepieces, without any setting.


Special technology able to double the light intensity for incomparable performance, ensuring constant pure-white colour temperature. Relevant money & energy saving thanks to the incredibly low energy consumptions allow you to cut the electricity bills by 90%! On SZO-3, SZO-4, SZO-5, SZO-6.


Money & energy saving thanks to LED long lifetime (65.000 hours, 20 years in case of 8 hours/day) which is more than 20 times compared to a standard halogen bulb. LED illumination is available as transmitted light, cold light and ring light illuminators. On SZO-3, SZO-4, SZO-5, SZO-6.
