Portable Polariscope With Flashlight & Case

This 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 properties—an essential test in gem identification. Features Determines isotropic vs. anisotropic gemstones Rotating top polarizing lens for observing optical reactions Diffused bottom lens for even light distribution Includes removable auxiliary lens (non-magnifying) Flashlight attaches securely to base with screw fitting Compact, portable design for bench or field use Includes zippered storage case Specifications Instrument Type Portable Polariscope Configuration Rotating Top Lens, Diffused Bottom Lens, Removable Auxiliary Lens Light Source Detachable Flashlight Manufactured In China What's Included Item Qty Portable Polariscope Main Body 1 Flashlight 1 Auxiliary Lens 1 Zippered Storage Case 1 Notes The included lenses function as polarizing and diffusing elements and do not provide magnification. Position the stone centrally between the filters and rotate the top lens to observe changes in light and dark areas during testing.
