Magesium Flouride (MgF2 is transparent over a extremely wide range of wavelengths .windows, lenses ,and prisms made of this materials can be used over the entire range of wavelengths from 0.12μm(vacuum ultraviolet ) to 8.0μm (infrared). High quality synthetic VUV grade MgF2 is quite expensive. Low grade MgF2 is sometimes used in the infrared but it is inferior to CaF2. MgF2 is tough and works and polishes well, but it is slightly birefringent and should be cut with the optic axis perpendicular to the plane of the window or lens.

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).
