The stereo microscopes of the SZN series are instruments designed for laboratory and industry applications. Their optical and mechanical qualities place them at the top of their category and the price/quality ratio is excellent. The stereo microscopes share the same optical system consisting of binocular and trinocular heads with zoom objectives. The four models of the SZN series find their proper application wherever professional instruments are required. Several accessories provide ample choices of configurations and applications.
Binocular or trinocular, 360° rotating and 45° inclined.
Adjustable between 55 and 75 mm. Dioptric compensation on both eyepiece tubes.
Parfocal achromatic zoom 0.67x …. 4.5x with continuously variable magnification (max. 45x in the standard configuration, can be increased to 225x by using additional accessories).
Except overhanging models, the instruments are fitted with a white disc for contrast and specimen clamps. Models with transmitted illumination also fitted with frosted glass disc.
By means of rack and pinion system, controlled by a pair of knobs.
The series has different stands for every requirement. Simple for vision without transmitted illumination; base for incident and transmitted illumination; overhanging stands (simple or hinged), that allow very large objects to be viewed and to be handled or worked.
