as the high precision optical components manufacturer in China, JUKA Optical can customize the optical windows. the material can be H-K9L,BK7, Fused Silica, visible optical glass, infrared optical glass, infrared optical glass, colored glass,etc.

the optical window is one of the basic optical components in optics, and it is an optical flat plate that plays a role in protecting electronic components / sensors / semiconductor components in the optical path. the optical window will not change the optical magnification, and only affects the optical path in the optical path. Mechanical properties such as light transmittance, surface accuracy, thickness, parallelism, and substrate material are important parameters of optical windows. You can choose the optical window with suitable parameters according to the specific application.

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.
