Portable Polariscope With Flashlight & Case Chasing & Stamping 3 CFM (120 L/min) airThis portable polariscope is designed to differentiate between singly refractive (isotropic) and doubly refractive (anisotropic) stones. By placing a gemstone between two polarizing filters and rotating the top lens, you can observe characteristic light reactions that reveal important optical propertiesan essential test in gem identification. Features Determines isotropic vs. anisotropic gemstones Rotating top polarizing lens for observing optical
