PRODUCT OVERVIEW
Introduction
CaF2 windows combine broad ultraviolet-to-infrared transmission with low optical dispersion, making calcium fluoride especially useful in systems where wavelength-dependent deviation must be minimized. Its relatively low refractive index also helps reduce surface reflection compared with many higher-index infrared materials.
Unlike materials chosen mainly for long-wave infrared coverage, CaF2 is particularly valued for maintaining balanced optical behavior across widely separated wavelengths. This makes it a strong choice for multispectral, spectroscopic, and precision optical designs where chromatic performance matters as much as transmission range.
Applications
- Multispectral imaging systems
- Thermal imaging equipment
- UV–IR spectroscopy systems
