The Baader UV/IR Block Filter is almost essential for astrophotography. Unfocused UV/IR rays refracted by the lenses can cause disturbing halos on the sensor, which can be completely eliminated by using this filter. Its outstanding quality is ensured by 98% light transmission, precisely manufactured optical glass, and a hard coating that provides excellent scratch resistance. The anti-reflection coatings deposited on the surfaces effectively minimize unwanted reflections.
The UV/IR filter is also available as part of a set with red, green, and blue filters, enabling colour imaging with monochrome sensors.
The filter also features an internal thread, allowing it to be combined with other filters.
