INFRARED POLARISERS & WAVEPLATES Infrared polarisers are extremely useful components in material analysis, infrared imaging, interferometry, pharmaceutical, microscopy and forensic analyses and many sectors of optical instrumentation. We supply a full range of polarisers in holographic, mechanical ruled and free standing wire grid types for varying applications and wavelengths from 1um to millimetre waves. Substrate materials include CaF2, BaF2, KRS-5, ZnSe and Ge in sizes up to 75mm diameter and free standing wiregrid polarisers up to 300mm diameter. They all have exceptionally high extinction ratios. Complementary waveplates are available. |
