Edmund Optics’ TECHSPEC high-energy laser line polarizers are used to efficiently polarize high-power lasers with greater than 98% transmission of P-polarized light. The polarizers combine high laser damage thresholds (2 J/cm2, 10 ns at 532 nm) with high extinction ratios of 10,000:1 for optimal performance in a wide range of laser applications. They are designed with a 45° angle of incidence and provide greater than 98% P-polarization transmission efficiency. A hard anti-reflective coating made with a UV-grade fused silica substrate provides good durability and allows for easy cleaning and simplified alignment. The devices are available for common laser wavelengths including 355 nm, 532 nm, 633 nm, and 1064 nm.
