Infrared Domes

  • Germanium domes is a special type of windows which is ideal for IR applications(especially for defense and aerospace application) with its broad transmission range and opacity in the visible portion of the spectrum. Germanium domes is commonly used in IR thermal imaging camears typically operating in the 2 µm to 14 µm spectral range, covers the LWIR (8-12μm) and MWIR (3-5μm) thermal imaging wavelength range. Germanium windows can be AR coated with Diamond (DLC coating or Hard carbon coating) producing an extremely tough front optic.
  •  Hot-pressed MgF2 domes for missiles and launch tubes is provided having high ultraviolet transmittance and high strength is mainly used as mid-infrared wave window material. It is used to produce mid-infrared wave vector dome. With high infrared transmittance, small thermal expansion coefficient, good mechanical property, and low preparation cost, it is the best material for mid-infrared wave vector dome.  
  • Hot-pressed Polycrystalline Zinc Sulphide is a kind of infrared optical material with a wide transmittance range. It is prepared from high pure zinc sulphide raw material under vacuum and high temperature condition. It possesses good infrared transmission and thermal property and high impact overloading resistance. Since it can be directly pressed into large size plates and spherical windows with various curvature radiuses, it has been extensively used in the infrared detector windows with various sizes. Besides, this product is still a kind of good coating material.
