Chroma Luminance Filter, 36 mm unmounted

This filter blocks UV and IR light, which improves image sharpness when using refractive optics.

In tri-color photography, it allows the entire light range covered by the three RGB filters to pass through, which, due to the shorter exposure time, enables a monochrome image with less effective air turbulence and thus higher image sharpness. Because the sharpness information for the human eye lies mainly in the differences in brightness, the lower sharpness of the color images is not important.
