Products Advantage
  • 01
    Conventional Processing
    Vital Optics can process a variety of high-precision laser and infrared windows, lenses, and rectifiers from conventional grind and polish technology. Materials include germanium, silicon, ZnS, ZnSe, GaAs, chalcogenide glass, magnesium fluoride, and other optical materials. The maximum processing aperture exceeds 300 mm, with high precision and excellent surface quality.
  • 02
    Diamond Turning
    Our ultra-precision single-point diamond turning lathe equipment can be used to process high precision and high finish optical components such as aspherical, diffractive, and free-form surfaces of various infrared materials and non-ferrous metals such as germanium, ZnSe, and chalcogenide glass. The maximum processing diameter is up to 700 mm with a surface roughness of Ra<1 nm and a shape error of P-V<0.1 μm.
  • 03
    Optical Coating
    Vital Optics’ workshops use advanced optical coating equipment and various coating technologies such as thermal evaporation (resistance heating and electron gun) coating, plasma-assisted chemical vapor deposition coating, and sputtering coating, to provide customers with products that can satisfy various coating requirements, including diamond-like carbon film, infrared enhancement film, laser damage resistance film.
