This is Shalom EO's 21212-002 ultrafast thin film polarizers. This is a plate-shaped plano-plano circular polarizer with >4J/cm2@1030nm, 200ps, 100Hz high laser-induced damage threshold. The 21212-002 femtosecond thin film polarizer, with a diameter of 12.7 mm and a thickness of 3 mm, utilizes thin film coatings of S1: Rs>99.9%@515nm, Tp>99%@515nm, delivering a high extinction ratio of 1000:1 to separate the s-polarization and p-polarization at 515nm wavelength for Ultrafast Ytterbium. The polarizer is oriented to be used at the AOI of 56° Brewster angle, which is why the back surface is uncoated.
