Calcite crystal is a negative uniaxial crystal well-known for its high
birefringence and transparence in broad region of spectrum. It is the
ideal material for manufacturing various polarizers used in visible-IR
range such as Glan-Taylor polarizers, Glan-Thompson polarizers and Glan
laser polarizers. Recently, calcite plate is also widely used for time
delay compensation between two orthogonally polarized ultrafast pulses.

Coatings
The AR coating is a multi-layer dual-band dielectric coating with the
minimal reflectances at the specified wavelengths.
Mount
For customer convenience and protection of crystals, all
crystals with the thickness =< 3.5mm are pre-mounted in a 1" ( 25.4 mm ) anodized aluminium
(Al) holder. A standard 1"
mirror mount may be conveniently used to tune the crystals for optimized
birefringence or time delay
(Mirror mount and post are not included).
A rotation stage may be further used if a larger angle change is needed.
1.5" (38.1mm) holders are available for xtals with large apertures.
