Fused Quartz optical window

K9 optical window

 

  • Quartz glass is an ideal UV material. It has high transmittance in the range of 220nm to 2500nm, good chemical stability and radiation resistance, low expansion coefficient, low fluorescence radiation and scratch resistance.

  • Optical window sheet is a parallel plane plate, which is usually used as a protective window for electronic sensors or detectors in the external environment.

  • When selecting a window sheet, the user should consider whether the transmission properties of the material and the mechanical properties of the substrate are consistent with the application requirements. The window slice does not change the magnification of the system.
