Description
Calcite is a naturally occurring birefringent crystal. By precisely controlling internal prism angles in these calcite polarizers, a very efficient linear polarizer is produced.
Meadowlark Optics offers Glan‐Thompson Polarizers, intended for precision optical instrumentation and low power laser applications. Key advantages of GlanThompson Polarizers include excellent extinction ratio performance and a broad spectral range.
Our Glan‐Thompson Polarizers are supplied in a black anodized cylindrical housing for easy mounting. The housing is marked to indicate the polarization axis of the transmitted beam. The rejected component of the beam is totally internally reflected and eventually absorbed by the anodized aluminum.
Although raw calcite material transmits down to 215 nm, the cement interface limits ultraviolet transmission. For this reason, we recommend Glan‐Thompson Polarizers for use over 320 –2300 nm.
Three antireflection coating options cover the visible to near infrared range. Uncoated Glan‐Thompson Polarizers are also available.
