Material

CaF2
         The CaF2 is an excellent material in laser optics field. It has very wide transmission range from 130nm to 9500 nm, especially, has the high transmission in IR range. CaF2 is widely used in Laser, IR and UV optics.

SiO2
        Silicon dioxide optical coating material is made of high purity silicon dioxide powder as raw material and adds appropriate useful elements to effectively control hazardous substances in silicon dioxide. It is melted under a temperature of above 2000 C and crushed after precise annealing. The material is high hardness and can be used in surface protection. It is widely used in optical filter lens production due to its small stress and easy filming, beside there is no other material which can replace silicon dioxide coating system and It is applied in ultra large scale integrated circuits in large quantity due to its also good electrical insulation.

BAF2
         BaF2 is relatively hard but is highly sensitive to thermal shock. For its transmission range is 0.2 m - 11 m, the material is used for optical windows, lenses and prisms in UV-IR. Besides it can also be used as substrate for some applications. BaF2 is less resistant to attack by water than CaF2. Pronounced water attack occurs at 500 C, but in a dry environment the material can be used to 800 C. BaF2 is grown by modified Bridgman technique. Maximum available size: 200 mm Dia x 50 mm Thk. Besides, BaF2 is usually used as scintillator for gamma detection. It is the fastest scintillating crystals up to now.

MgF2
        Magnesium Fluoride (MgF2 crystal) is used for optical elements where extreme ruggedness and durability is required. Its useful transmission range is 0.11 m - 8.5 m. MgF2 single crystals is a positive crystal and slightly birefringent and usually supplied with the optic axis cut perpendicular to the window faces.

LiF
        LiF shows excellent transmittance in the VUV region. It is used for windows, prisms, and lenses in the visible and infrared in 0.104 m - 7 m. LiF is 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. For good structure LiF is less commonly grown by the Kyropoulos method (air-grown) specifically for monochromator plates. High quality LiF is usually grown by modified Bridgman technique. Maximum available size in diameters is 115mm. LiF is slightly plastic and can be bent into radius plates.
