The Baader UV/IR Cut / L-Filter 36 mm (article 2459421) is an unmounted round luminance filter with 2 mm glass thickness for imaging with DSLR, CCD and modified webcam cameras. It blocks ultraviolet and infrared light either side of the visible band so stars stay tight and free of colour halos.

Its optical quality allows it to be stacked and used well ahead of the focal plane, and it can be combined with other Baader filters such as the Contrast Booster.

Key Features

  • UV and IR blocking – Cuts UV below the visible band and IR beyond the deep red, reducing bloated star images.
  • Passes H-alpha – Visible red including the 656 nm H-alpha line is transmitted.
  • High transmission – Average transmission of about 98% in the passband.
  • Ghost-free – Low-reflection multi-coating on a striae-free, plane-parallel substrate.
  • Stackable – Can be combined with other Baader filters and used far ahead of focus.
