Optogama ultrafast 72° thin-film polarizers are designed for a broad wavelength range and typically used in femtosecond laser systems. A total of 4 configurations are available: transmission polarizers optimized for highest transmission of p polarization (Tp) or highest contrast of polarizations (Tp:Ts) and reflection polarizers optimized for highest reflection of s polarization (Rs) or highest contrast (Rs:Rp). Transmission polarizers have the output face AR coated for p polarization, while reflection polarizers are AR coated for both s and p polarizations. Standard wavelength range is 750-850 nm and can be customized upon request.
