The Baader UV/IR filter is an almost "essential" piece for users of digital cameras photographing with achromatic refractors. The unfocused UV/IR rays by the lenses cause a disturbing "halo" on the CCD chip, which can be completely eliminated with the use of the filter. The device's high quality is guaranteed by its 98% light transmission rate, the excellently crafted optical glass, which is highly resistant to scratches thanks to its hard coating. Naturally, it can be combined with other filters, and its surfaces are equipped with anti-reflective coatings for impeccable imaging.
The UV/IR filter is also available in a set with red, green, and blue filters, opening up the possibility of creating color images even with monochrome sensors.
