Polarizer, Glan-Thompson Calcite, 25.4 mm Diameter, Uncoated

glan-thompson calcite polarizer model 10gt04

The 10GT04 Glan-Thompson Calcite Polarizer provides high purity linear polarization for broadband sources or multiple laser wavelengths. The large acceptance angle of this polarizer allows it to be used in highly converging or diverging beams. S-polarization is transmitted with Ts >90%, while p-polarization is reflected and absorbed into the housing. Our Glan-Thompson polarizers are fabricated from select-grade calcite prism pairs, cemented together and assembled into a black anodized aluminum housing. The cemented surface limits their use to lower power applications. The output polarization axis is clearly marked on the housing. The housing has been designed to mount into our standard 25.4 mm optic holders, rotary stages, and precision positioning components. This polarizer is uncoated.

**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. **
