Wollaston Prisms separate the unpolarized light into two orthogonally polarized outputs with an angle of separation based on the prism material, typically from 1 to 20 degrees. Currently, two materials in use are Quartz and calcite. Typically, the extinction ratio is more than 10000:1. The crystal quartz and calcite are capable on the wavelength range of 660nm to 1550nm and theoretically from 400nm to 2000nm and 350nm to 2300nm, respectively.<\/p>

Calcite polarizers are birefringent calcite crystals. Due to the birefringent nature of calcite, waves\u00a0<\/span>polarized in the direction of the optical axis propagate with a different index of refraction than\u00a0<\/span>waves polarized orthogonally to the optical axis. The birefringence separates the two orthogonal\u00a0<\/span>polarization states of an incident beam. A calcite polarizer can be designed as either a polarization\u00a0<\/span>splitter\/combiner or as a polarizer element that removes the angled, orthogonally polarized\u00a0<\/span>component of a beam. Our calcite polarizers are typically built out of two prisms, as shown in the\u00a0<\/span>drawing to the right. Since calcite is a soft crystal that is easily damaged, almost all calcite\u00a0<\/span>polarizers can be offered in metal housings. With convenient threading and adapters.<\/span><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t
