Custom Optical Window Ar Bbar Anti Reflective Coating UV Fused Silica Window

Optical windows are applied to isolate different physical environments while allowing light to pass. When selecting flat window you should consider materials, transmission, scattering, wave front distortion, parallelism and resistance to certain environment. JUKA Optical offers a wide range of different materials and different degree of precision optical window glass, such as bk7 window, UV fused silica window, quartz window, znse window,etc. Material BK7 and Fused silica typically, Visible optical glass, Infrared optical glass, Colored glass.
