Diamond turned aspheric lenses are typically used in missile guidance systems, night vision/thermal Imaging cameras and other military based and commercial infrared systems. Knight Optical offers diamond turned aspherics from several infrared materials including Germanium (Ge), Calcium Fluoride (CaF₂), Zinc Sulphide (ZnS), Zinc Selenide (ZnSe), Aluminium (Al) and chalcogenide glasses like AMTIR (Ge33As12Se55 ). Lenses can be coated with a range of antireflective coatings, e.g. for MWIR (AR/DLC coated 3 to 5µm) and LWIR (AR/DLC coated 8 to 12µm).
