The OPTIGEM-1 and OPTIGEM-2 Microscopes are a revolutionary 2-in-1 gemmology 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 wide range of optional accessories completes these intruments: from gemology clip (included), an iris aperture diaphragm (included), a polarization analysis kit, an optical unit to switch the dark field from a "sharp" (gem exhibition) to a "soft" (diamond analysis) mode (included), translating cell holder with vacuum pick-up and quartz immesion 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.

Includes: ST-201: Iris aperture diaphragm. Creates a soft darkfield illumination ideal for diamond analysis.
