Due to substrate absorption, scattering and reflection , the transmittance of IR lenses is limited in each wavelength, also need to improve the reflectivity for application demand, and lens used in different environments, such as high temperature and high humidity, sandstorm and other harsh environment etc., Leading to make the lens achieving a variety of the application requirements by the coating technology ,so the coating plays a very important role in infrared system.

AR(Anti-Reflection) BBAR(Broadband Anti-Reflection)
HR(High Reflection)/Mirror Phase Retarder
Filter DLC(Diamond-Like Carbon)
