IR/UV CUT FILTERS
The IR/UV-CUT filters are designed to block ultraviolet and infrared wavelengths and to capture the luminance in monochrome cameras.
Also, this filter is needed to cut off unwanted wavelengths in colour cameras which are sensitive to these radiations. Using one shot colour cameras without these filters will cause unnatural colour balances. In refractors, the IR/UV cut filters are highly recommended to reduce the chromatic aberration, even in apochromatic telescopes as they are not corrected outside the visible spectrum.
