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.

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

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.

This is the most common type of lens element.  It can be used to focus, collect and collimate light.  It is also useful as a simple imaging lens

Plano-concave glass lenses are manufactured with one concave surface and one plane surface. These lenses have negative focal lengths.

MIR coating will be used more and more usually .Mostly, it is used militarily .Such as night vision instrument ,light will be reflected very seriously without this kind of coating. The coating can help the mid-infrared light go through the crystal material.

FIR coating will be used more and more usually .Mostly, it is used militarily .Such as night vision instrument ,light will be reflected very seriously without this kind of coating. The coating can help the far-infrared light go through the crystal material.

"UV coating" refers to surface treatments which are either cured by ultraviolet radiation, or protect the underlying material from its harmful effects. Common uses of UV coating include eyeglasses and automotive windows. Photographic filters remove ultraviolet to prevent exposure of the film or sensor by invisible light.

VIisible coating will be used more and more usually .Mostly, it is used militarily.Such as night vision instrument ,light will be reflected very seriously without this kind of coating. The coating can help theVisible light go through the optical materials
