GLAN TAYLOR

 

The Glan Taylor prism polarizer is made of two calcite prisms which are assembled with an air space . It has a length to aperture ratio of approximately 1.0 which makes it a relatively thin polarizer. It is made of UV selected calcite. A 10 mm thick calcite  plate having 50% or more transmission at 250 nm is considered UV selected. The spectral range of this polarizer is from 250-2300 nm. Below 250 nm, transmission cutoff wavelength varies from crystal to crystal.

 

Specifications :

 

B grade calcite

: greater than one wave wavefront deformation @ 633 nm due to striae  only

A grade calcite : quarter to one wave wavefront deformation @ 633 nm due to striae only
S grade calcite : quarter wave wavefront deformation @ 633 nm due to striae only
E type : made of S grade calcite but polarizer has beam deviation of one instead of three arc minutes
surface flatness : at least quarter wave @ 633 nm over the clear aperture
surface quality : 40-20 scratch dig
transmission ( uncoated ) 

: 25-30% at 250 nm, 40-45% at 300 nm,  65-70% at 400 nm and 85-87% at > 500 nm

Calcite is a natural  mined crystal . Defects in bulk calcite are characterized by bubbles ( presence of randomly scattered bubbles vary from relatively large to small sizes and fine bubble lines), striae ( streaks of sudden variation of refractive index which can be detected interferometrically ), optical inhomogeneity ( gradual variation of refractive index in bulk material ) and stress birefringence ( variation of birefringence in bulk material due to defective growth of the crystal ). These defects cause degradation of polarization and transmission loss due to scattering and absorption.
