Abstract

The invention relates to the technical field of infrared optical coating, and provides a 10.3-10.9 mum high-strength anti-reflection film on a ZnSe substrate. The structure of a film system is G/100L1010H901L10H933L10H/A. The invention further provides a coating method of the 10.3-10.9 mum high-strength anti-reflection film on the ZnSe substrate. The APS ion source high-energy assistance and substrate heating film coating mode is adopted. The high-strength antireflection film has the beneficial effects that after the two surfaces of the ZnSe substrate are coated with the high-strength antireflection film, the average transmittance of 10.3-10.9 mum reaches 99% or above; and moreover, the requirements of abrasion resistance, constant damp heat, low temperature and salt spray environment tests in the JB/T 8226.1-1999 optical part coating standard are met.

Description

Technical field [0001] The present invention relates to the field of infrared optical coating, and more particularly to a ZnSe substrate 10.3-10.9 μm high strength reduction membrane, further involves a plating method of 10.3-10.9 μm high-strength reduction film in a ZnSe substrate. Background technique [0002] With the development of military infrared technologies, there are more and more applications in infrared optical systems, and an indispensable optical component in the infrared system such as airborne, carrier, and tank infrared imaging system needs. A substantial increase. The selenium selenium material is a yellow-transparent polycrystalline material with a crystalline particle size of about 70 μm, and the light transmitted range is 0.5 to 15 μm, and the scattering loss is extremely low in impurity absorption. Since the absorption of 10.6 μm wavelength light is small, the preferred material for making the optical device in the high power laser system is formed. Furtherm...
