Baader LRGB 31mm Filterset – CMOS-optimized

Highlights

• Baader CMOS LRGB Band-pass Filter Set, 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
• Including UV/IR cut (L-filter) with 98% transmission over the entire visible spectrum from 420 - 685
• 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 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 a most adverse environment
