GEMZ-8TR Gemological Trinocular Zoom Stereo Microscope (Japan)

The GEM Series of professional gemological microscopes are based on Meiji Techno (Japan) EM Series stereo microscope bodies. These gem stereoscopes have earned Meiji Techno a great reputation for excellent optics, rugged dependability, versatility, and economy that no other manufacturer can match. Choose from zoom bodies or turret bodies mounted on a full-sized gem stand that offers powerful darkfield transmitted illumination suitable for photomicrography. Systems are equipped with a 2-stage fluorescent incident illuminator useful for viewing inclusions. All models are available in either 115V or 220/240V. All GEM Series microscopes come with dust covers, and rubber eyeshields.

Superb Optics:
Multi-coated optical components, free form chromatic and spherical aberration, provide crystal-clear, high resolution images. The Greenough optical design provides superior erect, unreversed, stereoscopic images, rich in contrast, brightness and correct in their original color.

Rugged Dependability:
All-metal aluminum alloy microscope bodies and components with chemical resistant finishes guarantee stability and rugged dependability for a lifetime of day-in and day-out use. Superior craftsmanship, quality components and materials result in long-lasting, high-performance products.

Ergonomic Design:
All GEM Series stereo bodies feature adjustable diopter tubes and interpupillary distance adjustment. Observation tubes are inclined at 45° for convenient fatigue free viewing. All GEM Series feature tilting bases for additional user comfort. A choice of a continuous magnification Zoom stereo body or a two-power Turret type stereo body. Optional eyepieces, supplementary lenses, 35mm and video camera components allows the user to design a system to fulfill their specific requirement.
