Dichroic Polarizers

  • Plastic sheet polarizers are convenient and useful for multiple purposes
  • Available with glass cover plates and mounting ring for rigidity and protection
  • Unmounted versions available up to 100mm in diameter
  • Single sheet transmission of 36%
  • Extinction ratio of 1 x 10-4 for high contrast applications

These are sheets of dichroic plastic material which provide a reasonable degree of polarization at an economical price. They are laminated between two thin sheets of glass for rigidity and mounted in a metal ring for ease of use and handling. The optic axis is marked.

These are broadband devices operating over a range of 400-750nm, and 760-2000nm.

We also offer economical unmounted sheets of this material which are neither sandwiched between glass covers nor mounted in the aluminum ring around the outside. The unmounted material has a slight tendency to curl in one direction.
