 Optimized for CMOS sensors (Color and MONO)
 Reflex blocker coating against reflections in combination with correctors placed near the filter
 Exact and narrow FWHM for optimal signal-to-noise ratio
 Identical filter thicknesses for parfocality (not parfocal to older Baader filters!)

 The front side is marked in the form of a black outer edge (front side indicator)
 The edge of the filter is sealed, so no moisture can get in
 Life-Coat - an even harder coating for a virtually unlimited lifetime
