This is Shalom EO's 21212-007 ultrafast thin film polarizers. This is a plate-shaped plano-plano circular polarizer with a >4J/cm2@1030nm, 200ps, 100Hz high laser-induced damage threshold. The 21212-007 femtosecond thin film polarizer with diameter 12.7mm and thickness 3mm utilizes thin film coatings of S1: Rs>99.9%@1030nm, Tp>99%@1030nm; S2: Rp<0.2%@1030nm, delivering high extinction ratio of 1000:1 to separate the s-polarization and p-polarization at 1030nm wavelength for Ultrafast Ytterbium at the 45° angle of incidence.
