Calcite Polarizer Type Calcite polarizers come in many configurations for specific polarization applications.
           
   Your choices are...         
   Glan Thomson Polarizers       Glan Thomson polarizer is useful for moderate power, visible wavelength applications. They have high extinction ratios, <10-5, and wide acceptance angles. 
   Glan Taylor Polarizers       Glan Taylor polarizers have large extinction ratios, and are ideal where the rejected beam is not required. 
   Glan Laser Polarizers       Glan Laser polarizers are a form of Glan Taylor polarizers that are intended for use with high power beams. 
   Wollaston       Wollaston provides a simple way to split a beam of light into two mutually orthogonal, linearly polarized beams, convenient for double imaging of a single source. 
   Other       Any other calcite polarizers.

   Extinction Ratio:       Excitation ratio refers to the ratio of the power of a plane-polarized beam that is transmitted through a polarizer placed in its path with its polarizing axis parallel to the beam's plane, as compared with the transmitted power when the polarizer's axis is perpendicular to the beam's plane. 
   Search Logic:      User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria.
   Transmittance:       Transmittance is the ratio of the radiant power transmitted by a polarizer to the incident radiant power. 
   Search Logic:      User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria.
   Diameter:       The diameter of the depolarizer when viewed straight on. 
   Search Logic:      User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria.
   Clear Aperture       This is the clear aperture of retardation plates. 
   Search Logic:      User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria.
   Length:       The length of the polarizer and housing. 
   Search Logic:      User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria.
   Beam Deviation:       The deviation of the polarized beam from normal. 
   Search Logic:      User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria.
   Operating Temperature:       The temperature range in which the device is designed to operate. 
   Search Logic:      User may specify either, both, or neither of the limits in a "From - To" range; when both are specified, matching products will cover entire range. Products returned as matches will meet all specified criteria.
