Gemax Polariscope 3M Micron Abrasive Wet Or Dry Polishing Paper 15 Micron (Grit 1200 Retractable thermoelectric probe tip thatThe Gemax Polariscope features a full visible light spectrum (400nm 700nm). Includes a conoscope (a strain free acrylic or glass sphere on a rod) used to determine optic character in gemstones. The table glass is 40mm (Diameter) and is located over the lower polariser. The polariscope is the fastest way to test the optical properties of gemstones, quickly determine whether translucent or transparent gems are singly or doubly refractive, resolve optic
