      - folds into casing for convenient compact size
      - a low-cost screening instrument

    • POLARISCOPE
      To test single or double refraction, optic character and pleochroism of transparent or translucent gems, both loose or mounted. It provides a quick and easy test for eliminating many possible identities of a gemstone.
      - intense diffuse coldlight lamp 25 watts
      - 50mm diameter rotating analysing filter
