Specification:

Optical Fused Silica JGS1 Flat Glass Windows Lens are flat, plane-parallel plates that are often used as protective barriers for electronic sensors or detectors from outside environments. Optical Fused Silica JGS1 Flat Glass Windows Lens should be selected based on the material transmission or mechanical properties of the substrate. Optical Fused Silica JGS1 Flat Glass Windows Lens do not cause change in the magnification of a system.
YuTai Optics' Optical Windows are offered in a variety of substrates, such as Germanium (Ge), Silicon (Si), N-BK7, UV Fused Silica, Zinc Selenide (ZnSe), or Potassium Bromide (KBr). Multiple anti-reflection coating options are available for the Ultraviolet (UV), visible, or Infrared (IR).
