Baader RGB-R 36mm Filter – CMOS-optimized

Highlights

• Baader CMOS RGB-R (595 – 690 nm) Band-pass 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 also 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 largest ever freedom from halos, even under most adverse conditions concerning aux-optics
• Identical filter thickness to existing standards, with utmost care for remaining Par focal
• 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 coated individually , with 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 the most adverse environment
