Baader RGB Filter 2" – CMOS-optimized

• Baader CMOS RGB-B (400 – 510 nm) Bandpass Filter, suitable from f/15 to f/1.8
• Anti-reflection RGB filter (red/green/blue) with extremely high transmission of the respective color channel, thus simultaneously reducing stray light and reflections to an unprecedented level
• Balanced RGB design allows subframes to be taken with the same exposure time – extremely important for automated imaging tasks
• Reflex-Blocker™ hard coated and plane optically polished – with sealed coating edges (Life-Coat™)
• Blackened edges all around, with filter-lead-side-indicator in the form of a telescope-sided black outer rim
• Optimized for modern CMOS cameras, but likewise excellent for CCD camera technologies

This new generation of Baader CMOS-filters features:

• Increased contrast, matched for typical CMOS quantum efficiency and s/n ratio
• Reflex-Blocker^™ coatings, for the largest ever freedom from halos, even under most adverse conditions concerning aux-optics
• Identical filter thickness to existing standards, with utmost care for parfocality
• Blackened edges all around, with filter-lead-side-indicator in the form of a telescope-sided black outer rim, to additionally eliminate any reflection due to light falling onto the edge of a filter
• Each filter is coated individually, with a sealed coating edge (NOT cut out of a larger plate with coatings left exposed, read more)
• Life-Coat™: evermore hard coatings to enable a non-aging coating for life – even in a most adverse environment
