This tabletop polariscope is designed to quickly differentiate between singly refractive (isotropic) and doubly refractive (anisotropic) stones. By placing a stone between two polarizing filters and rotating the upper lens, you can observe characteristic light changes that reveal a stone’s optical behavior—an essential step in gemstone identification.

Features

  • Designed to distinguish isotropic from anisotropic stones
  • Rotating top polarizing lens for observation of interference effects
  • Diffused bottom lens for even illumination
  • Additional removable lens positioned above the bottom lens
  • Integrated illumination with rear on/off switch
  • Tabletop design for stable gemological examination
  • No batteries required

Notes

The included lenses function as polarizing elements and light diffusers; they do not provide magnification. For proper operation, connect to a compatible 110–120V outlet and ensure the stone is centered between the polarizing filters before rotating the top lens.
