Monochromatic Light Illumination Gem Microscope Optical gemological instrument
FGM-R5S-11
Five generations of swing arm base:
★Atmospheric classic base, which can rotate 360°;
★The lens body can be adjusted freely within the range of 0-45°; ball-type guide rail; adjustable self-locking mechanism; installation holes for gem clips on both sides;
★Provide four lighting modes: bright fields, dark fields, top light and side light;
★10W high-power continuously adjustable LED bottom light imported from the United States, energy-saving and efficient; assembly beam diameter 2-42mm continuously adjustable large light barrier;
★The ring-shaped dark field diffuser has no screw fixing design, minus screw image interference, providing high-quality dark field;
★The top light is a 6W continuously adjustable ultra-high brightness LED white surface light source, and the color temperature of 6500+500K meets the requirements of diamond grading lighting;
★3W high-brightness adjustable LED side light auxiliary lighting;
★The orthogonal polarization conoscopic system is added to increase the key identification basis for gemstones under orthogonal polarization; integrated global wide-voltage power supply, stable brightness.
