Edmund Optics Inc. 40mm Dia. Calcium Fluoride Window, Uncoated NT63-209

Description
Low Absorption, High Transmission UV Grade Calcium Fluoride Ideal for Applications Ranging from 250nm thru 7µm Low Index of Refraction Calcium fluoride is often used in spectroscopic windows and lenses due to its high transmission from 250nm to 7µm. Its low absorption and high damage threshold makes it a popular choice for excimer laser optics. Calcium fluoride's low index or refraction allows it to be used without an anti-reflective coating. The Knoop hardness of calcium fluoride is 158.3. TECHSPEC® Calcium Fluoride (CaF2) Windows manufactured from vacuum UV grade calcium fluoride are commonly found in cryogenically cooled thermal imaging systems.
