Windows are applied to isolate different physical environments while allowing light to pass through.When selecting windows,it’s impossible to consider materials, transmission, scattering, wave front distortion, parallelism and resistance to certain environment. Lasertec can provide windows made from variety of materials as BK7,UVFS,Ge,Si,YAG,Sapphire, The application from UV to IR wavelength band with Single layer or multiplayer anti-reflecting coatings on optical windows used by instrument, medical, scanner and lasers.
