Please contact us for more information.

Lithium Fluoride is used for windows, lenses and prisms in the Vacuum UV, UV, visible and infrared where transmission in the range 0.104µm to 7µm is desired. Transmission is about 40% at 121nm.Modest precautions should be taken against moisture and high energy radiation damage.
LiF is attacked by atmospheric moisture at 400C, and softens at 600C. LiF is sensitive to thermal shock. Irradiation produces color centers. The material can be cleaved along (100) and less commonly (110). Although the optical characteristics are good the structure is not perfect and cleavage is difficult. VUV grade LiF windows are available. This is the best VUV transmitter available.

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).
