50.4 mm Baader RGB-R Ø filter optimized for CMOS

50.4 mm diameter 50.4 mm diameter Baader RGB-R filter optimized for CMOS

This new generation of Baader CMOS filters features:

• CMOS-optimized Baader filters
• Higher contrast, combined with typical CMOS quantum efficiency and s/n ratio
• Reflex-Blocker™ coatings, for the greatest freedom from halos, even under the most adverse conditions related to auxiliary optics
• Filter thickness identical to existing standards, with extreme care for parafocality
• Blackened edges all around, with filter lead-side indicator in the form of a black outer edge on the telescope side, to additionally eliminate any reflections due to light falling on the edge of a filter
• Each filter individually coated, with sealed coating edge (NOT cut from a larger plate with exposed coatings)
• Life-Coat ™: increasingly hard coatings to allow for a coating that will not age for life, even in the harshest environment

General Features:

• Baader RGB-R 50.4 mm x 3 mm (595 - 690 nm) bandpass filter, suitable from f/15 to f/1.8
• RGB anti-reflection filter (red / green / blue) with extremely high transmission of the respective color channel, simultaneously reducing stray light and reflections to an unprecedented level
• The balanced RGB design allows taking subframes with the same exposure time, which is extremely important for automated imaging tasks.
• Reflex-Blocker ™ hard-coated and planoptically polished, with sealed coating edges (Life-Coat ™)
• Blackened edges all around, with filter lead-side indicator in the form of a black outer edge on the telescope side
• Optimized for modern CMOS cameras, but excellent for CCD camera technologies
