• Introduction：

Lithium fluoride (LiF) crystal is a commonly used infrared materials with the smallest refractive index. Its transmission spectrum ranges from 120nm to 7000nm. It is usually used in lenses, prisms and windows of thermal imaging systems, aerospace optical systems and excimer laser optical systems.

• Applications：

1) X-ray monochromator plates UV photomultiplier tubes

2) Optical material for VUV applications

3) Windows, prisms, and lenses
