Lithium Fluoride (LiF) Windows provide high, flat transmission from 150nm to 6μm. Lithium fluoride has excellent transmission in the vacuum ultraviolet (VUV) wavelength range of 150 – 200nm. Lithium fluoride also has a low index of refraction, allowing these windows to be used without an anti-reflection (AR) coating. Lithium Fluoride (LiF) Windows are ideal for use as UV transmission windows in spectroscopy applications, as a diffracting element in X-ray spectrometry, or as infrared windows for thermal imaging applications.
Note: Lithium fluoride is sensitive to thermal shock and is attacked by atmospheric moisture at temperatures above 400°C.
