The Gemological Microscope Optigem are revolutionary 2-in-1 gemology instruments that can be used both as a vertical and as a horizontal microscopes, at the turn of a knob and without disassembling any part.
An ultra bright LED-based electronic condenser with intensity control, allows to switch from bright to dark field; it also produces perfectly the color of daylight. The condenser uses a new optical configuration especially created in order to obtain a perfect dark field application. An additional flexible arm and velvet-field slider produces for extra contrast, crisp and vibrant images even in a brightly lit environment.
A wide range of optional accessories completes these instrument from gemology clip, an iris aperture diaphragm, a polarization analysis kit, an optical unit to switch the dark field from a “sharp” (gem exhibition) to a “soft” (diamond analysis) mode translating cell holder with vacuum pick-up and quartz immersion cells complete and enhance the instrument usability. All the accessories can be stacked, in any order, while using the microscope in either horizontal or vertical configuration. The microscope body can be rotated through a full 360°, yet keeping the base sturdly fixed on the table, to show gems to a customer, or to share opinions with a colleague.
Heads: Diopter adjustment on both eyepieces. Interpupillary adjustment 51-75 mm.
Eyepieces: Widefield eyepieces WF10x/20mm with field number 20.
Objective: Parfocal achromatic objective 1x. Working distance: 100 mm.
Specimen stage: Specimen clamps. Adjustable gemology clip.
Focusing: By means of a rack and pinion controlled by a pair of knobs placed on both sides of the stereomicroscope.
Illumination: Incident illumination dichroic halogen lamp (12V/15W) with angle and brightness adjustment.
Transmitted illumination: pure white (6300K) LED system for observation in bright field (with diffusive LED disc) and dark field (with side-emitting LED ring).
Through a selector it’s possible to choose between 3 modes: bright field only, dark field only, or both bright field and dark field. Provided with a lever for the insertion of a black background in order to improve the dark field observation.

OPTIGEM 3 Microscopes are a revolutionary 2-in-1 gemology instruments that can be used both as a vertical and as horizontal microscopes, at the turn of a knob and without disassembling any part.
A special ultra bright LED-based electronic condenser, with intensity control, and yet always perfectly color-matched to sunlight, allows to switch from bright to dark field at the flip of a switch.
The condenser uses a novel optical configuration for an impressive dark field usability range, that will make you totally forget those uncomfortable hours spent “looking for light”. An additional flexible arm and velvet-field slider allow for extra contrast, for crisp and vibrant images even in a brightly lit environment.
A modular optional accessory range, that includes gemology clips, an iris aperture diaphragm, a polarization analysis kit, an optical unit to switch the dark field from a “sharp” (gem exhibition) to a “soft” (diamond analysis) mode and a translating cell holder with vacuum pick-up and quartz immersion cells complete and enhance the instrument usability.
All the accessories can be stacked, in any order, both when the microscope is being used as a horizontal unit and when it is in its vertical configuration.
The microscope body can be rotated through a full 360°, yet keeping the base sturdly fixed on the table, to show gems to a potential customer, or to share opinions with a colleague.

Zoom Stereo Microscopes provide a 3-dimensional or "stereo" image when looking through the microscope. The zoom feature on the stereo zoom microscope provides a range of viewing possibilities, and is the single feature that is most useful when selecting a stereoscope. The zoom knob on a stereo microscope provides magnification within a large range (for example, 0.7x - 4.5x) and ultimately allows the ability to view every single magnification (7x, 8x, 9x, etc.) when zooming in on the microscopy sample.
Stereo zoom microscopes allow quick zoom from low to high magnification. Using a stereo zoom microscope makes it simple to view a sample in the entire field of view, then focus and zoom in on a particular part of interest.
How Is Stereo Microscope Magnification Calculated:
Stereo microscope magnification is calculated by multiplying several variables including:
For example, if you are looking through a stereo microscope that has 10x eyepieces, a zoom knob that is set to 2.5x and the stereo microscope has a 1.5x auxiliary lens on it, the total magnification of that stereo microscope at the current setting is 10 x 2.5 x 1.5 = 37.5x magnification. If you were to remove the stereo auxiliary 1.5x lens, then the magnification would be 10 x 2.5 = 25x.
