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

What's Included

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.
