Germanium windows are polished to high precision quality. Wint Corporation offer broadband anti-reflection coatings, diamond-like carbon (DLC) coatings as well as metallization coating along the perimeter. DLC coating offers high hardness, corrosion resistance, wear and abrasion resistance. Design and manufacture high image quality infrared lens assemblies which are used on thermal imaging cameras. Wint Corporation offer wide range lens assemblies with various focus types and working for different sensors. Germanium has good transmission in long wave range 8-12 μm and is widely used in thermal imaging applications. Germanium lenses can be precisely generated by single-point diamond turning machine. Multiple diamond turning machines are operated in our facility. Wint Corporation have solid experience in making precision aspheric and diffractive surfaces. The finished parts can be tested with complete metrology.
