The 10GT04AR.16 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 has Newport's AR.16 NIR broadband antireflection coating with a 650 to 1000 nm wavelength range.
