Broadband Thin Film Laser Polarizers (at 70°) SKU: 420-1657BBi70
Broadband thin film polarizers separate the s- and p-polarization components in broad region at 70° angle of incidence (AOI). These polarizers are designed to be used in high energy laser systems, typically as extracavity attenuators for femtosecond lasers. Polarizers are made…
