Material

LiF
        Lithium Fluoride crystal is the common optical material with minimum refractive, and its spectral range is 120nm-7000nm. Usually, it is processed to prisms,lenses and windows used for thermal Imaging System, Space optical system and excimer laser system. However, Lithium Fluoride crystal is with high aqueous solubility and coefficient of thermal expansion, which is need to special measures to prevent it from deliquescence and deformation.

ZnSe
         Zinc Selenide (ZnSe) is a relatively soft material that scratches easily and it is not recommended in harsh environments because its Knoop Hardness is only 120. When handling, apply uniform pressure and wear Latex finger cots or gloves to prevent contamination.
Detail..

Sapphire
        Sapphire crystal is use for optical window lenses and Nitride Based Devices (Blue LEDs) . It has the following outing properties: outstanding physical-chemical properties, extraordinary mechanical resistance, high hardness, high optical resistance, resistance against high temperatures, high thermal conductivity, low electric conductivity, extremely low dielectric constant, strength even under extreme temperature conditions ,outstanding chemical resistance even against fluorination agents, perfect crystal lattice.

GE
        Germanium is a chemical element with the symbol Ge and atomic number 32. It is a lustrous, hard, grayish-white metalloid in the carbon group, chemically similar to its group neighbors tin and silicon.
Detail..

Silicon
        silicon is the most common metalloid. It is a chemical element, which has the symbol Si and atomic number 14. A tetravalent metalloid, it is less reactive than its chemical analog carbon.
Detail..

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.
