Product Series Overview

Glan-Laser Calcite Polarizers

The 10GL08 Glan-Laser Calcite Polarizer is designed for demanding applications requiring extreme polarization purity and high resistance to laser damage. Glan-laser polarizers are air-spaced, select-grade calcite prism pairs with the prism interface angles optimized for minimum insertion loss. Two escape ports provide an exit for the rejected polarization component, avoiding dangerous absorption of laser power by the polarizer housing. This allows this polarizer to be used in Q-switched laser cavities and other multiple pass applications.
This polarizer is uncoated. The housing has been designed to mount into our standard 1 inch (25.4 mm) optic holders, rotary stages, and precision positioning components. The output polarization axis is clearly marked on the housing.

**Calcite polarizers are made with natural crystals, and even in the best grade of calcite, there are embedded flaws which can not be corrected. The laser damage threshold value below was given for reference only and can not be guaranteed. **
