Raman Calcium Fluoride Windows

The transmission range of non fluorescent Raman grade calcium fluoride window is 130nm to 10 μ m, suitable for various spectroscopic applications from deep ultraviolet to mid infrared; In the wavelength range of 193nm to 7.87 μ m, the transmittance exceeds 94%. This material has low fluorescence properties, making it excellent in Raman spectroscopy analysis. Calcium fluoride has low dispersion (Abbe number 95) and low refractive index (about 1.4), which helps reduce chromatic aberration in optical systems. Has good chemical stability under most environmental conditions, but should avoid prolonged exposure to moisture. Applied to Raman spectroscopy analysis; Optical instruments and lasers; Infrared imaging and spectroscopy; Astronomical observations, etc. The non fluorescent Raman calcium fluoride window has become an important component in various high-precision optical applications due to its excellent optical properties and wide spectral range.
