Infrared polarizers on substrates, including CaF2, BaF2, ZnSe and KRS-5, have been introduced by Optometrics USA Inc. These holographic wire grid polarizers have 2400 grooves per millimeter and are suitable for applications requiring performance beyond 30 µm (using KRS-5). They have an extended infrared range and deliver high transmission and high extinction ratios. The polarizers are mounted in a double protective ring and have a substrate thickness of 2 mm and dimensional tolerance of ±0.5 mm.
