Barium Fluoride BaF2 Window High Thermal Expansion Coefficient For Optical System
Product description:
Barium Fluoride BaF2(IR) Crysta is transparent from the ultraviolet to the infrared, from 150-200nm to 11-11.5 μm, and can be used as a material to make optical components such as lenses The properties of single crystal and polycrystal are basically the same, the material is difficult to produce a single crystal, so the price of single crystal is 1 times that of polycrystal. Barium fluoride crystals are ideal materials for making optical components such as optical windows, prisms, and lenses. Can be used for infrared distribution cabinet windows, Fourier gas analysis windows, oil and gas detection, high power lasers, optical instruments, etc.
