Optika Optigem-1 Binocular Stereozoom Microscope

Binocular gemological stereomicroscopes for brightfield and darkfield applications with special side-emitting LED illumination ring for true darkfield illumination. Equipped also with an incident LED flexible arm and a diffusive LED disc for transmitted illumination. The instrument can be easily tilted horizontally for immersion analysis.
Features:

Observation mode: Brightfield, darkfield.
Heads: Binocular, 45° inclined, 360° rotating.
Interpupillary distance: Adjustable between 51 and 75 mm.
Dioptric adjustment: On both eyepiece tubes.
Eyepieces: WF10x/21 mm, high eye-point.
Objective: Parfocal achromatic zoom 0.7x…4.5x (zoom factor 6.43:1).
Working distance: 100 mm.
Specimen stage: Gemological stage, with clamp for holding gems.
Focusing: Rack and pinion mechanism controlled by a pair of knobs.
Stand: Fixed arm stand with tilting system (with position lock control). It can be totally overturned and rotated allowing in this way to obtain a 2-in-one instrument: an instrument for standard observations and one for observation of water-immersed gems.
Darkfield illumination: Equipped with a state-of-the-art illuminator for darkfield observation. It consist of an innovative side-emmiting LEDs ring with an emission angle of 38°. With brightness control.
Transmitted light llumination: Equipped with a LED illuminator, located under the stage. With brightness control.
Incident illumination: Equipped with a flexible gooseneck-arm LED illuminator. With brightness control.
Color temperature: Pure white 6,300 K
