    Crystalline Polarizers

    Crystalline Polarizers rely on the effects of birefringence in crystalline materials to modify the polarization of incident light. The transmission of the desired polarization and deviation of the remaining is related to the index of refraction of the birefringent materials and the angles of the cut between the crystals. Crystalline Polarizers typically consist of two birefringent crystals cut and aligned at specific crystalline axes to gain a particular polarization behavior, such as Lyot Depolarizers which take incident polarized light and output unpolarized light. Crystalline Polarizers have a high optical purity making them ideal for many laser applications requiring high damage thresholds with superior extinction ratios.

    Edmund Optics offers Glan-Type polarizers in three configurations including Glan-Laser, Glan-Thompson, and Glan-Taylor, as well as Lyot Depolarizers. All Glan-Type polarizers transmit the extraordinary beam, while deflecting the ordinary. Designed for high powered laser applications, Glan-Laser polarizers feature high optical quality crystals in conjunction with advanced polishing, making them an excellent high-power polarizer.
