BaF2 Windows,UV and IR windows In the most general sense, an optical window is flat piece of material, transparent at some portion of the electromagnetic spectrum from UV to IR, that allows the desired portion of the spectrum to pass into an optical instrument unaltered. Windows are commonly used as reference surfaces, beamsplitters, or as a layer of protection between an optical instrument and the environment.
BaF2 Windows can be used in a variety of applications, such as infrared spectroscopy, due to their wide broadband transmission that extends from the deep ultraviolet to the long-wave infrared.
