BaF2 Single Crystal Window

Barium Fluroide(BaF2) is a key material in the field of optics,famous in it's broad transparency range from ultraviolet( UV) to Infrared (IR) spectra.This wide transmission range make it ideal for variety of applications including ultraviolet and infrared spectra, optical windows and optical lenses in imaging system.

BaF2 has a low refractive index and low disperson helping to minimize chromatic aberratiions in optical systems, in additions it's show good resistance to radiation damage, making it suitalbe for high radiation environments such as space and nuclear applications. BaF2 combines optical clarity durability and thermal stability , make it versatile material for advanced optical technology.

Barium fluoride (BaF2) crystal window have a high operating temperature, good moisture resistance, melting point 1386℃,transmission more than 90% from 0.2um-10um,compare with CaF2 window, BaF2 window have better characteristic, that is radiation resistance, working on 800℃ high temperature, no water resistance, usually used as a protective window for electronic sensors or external environment dectors

BaF2 window also used on 8-14um as thermal imaging window and high energy physics laboratory.

BaF2 windows are the ideal material for making windows, prisms, lenses, AR coating or uncoated as customers demand
