LiF Optical Crystals7

1. Product Name:LiF Optical Crystals

2. Product Description:DescriptionLiF (Lithium Flouride) crystals shows excellent transmittance in the VUV region. It is used for windows, prisms, and lenses in the visible and infrared in 0.104 µm - 7 µm. LiF crystalis sensitive to thermal shock and would be attacked by atmospheric moisture at 400°C. In addition irradiation produces color centers. Modest precautions should be taken against moisture and high energy radiation damage. Besides LiF is softens at 600°C and is slightly plastic that can be bent into radius plates. 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. High quality LiF is usually grown by modified Bridgman technique.Lithium Flouride shows good optical properites. It can be used for windows, prisms and lenses in the vacuum UV,visibel and infrared. Because of its paricular lattice structure, LiF can also be used as X-ray diffraction devices.
