Cyan-Blue Selective Absorption Glass Filters are optical filters that effectively absorb light in the cyan and blue wavelength ranges. They are designed to selectively filter out cyan and blue light while allowing other wavelengths of light (such as red and green) to pass through. These filters are primarily used in applications requiring the suppression of cyan and blue light and optimization of spectral response, and are widely used in various fields such as optical imaging, color correction, spectral analysis, and environmental monitoring.
