Raman Grade Calcium Fluoride

Non fluorescence Raman grade calcium fluoride, also known as fluorite, is a relative concept, and most are also called Raman grade calcium fluoride. It is directly related to the application wavelength and laser energy of the material. For example, 450NM without fluorescence does not mean 355NM without fluorescence, and 2W laser without fluorescence does not mean 5W laser without fluorescence. Fluorescence can cause strong absorption, leading to energy loss, signal distortion, or imaging disorder. Fluorescent products are all materials that need to be selected or customized products, monitored through fluorescence spectrometers, energy spectrometers, or extreme ultraviolet irradiation. It can process shapes such as circular, rectangular, perforated, crescent, wedge-shaped, flat convex, flat concave, double convex, double concave, open ball, and prismatic.
