UV GLAN THOMPSON

 

The UV Glan Thompson prism polarizer is made of two calcite prisms cemented together with UV transmitting cement. It has a length to aperture ratio of approximately 2.0 : 1. It is made of UV selected calcite. A 10 mm thick calcite plate having 50%  or less absorption at 250 nm is considered UV selected. Spectral range of this polarizer is from 250 to 2300 nm. Below 250 nm, transmission cut off 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 arc minute

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, 70-75% at 400 nm, 83-87% at > 500 nm

Calcite is a natural  mined crystal . Defects in bulk calcite are characterized by bubbles ( presence of randomly 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.
