Dichroic polarizer

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 380-750nm, 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.
