Description
- 2" x 2 mm Baader LRGB Bandpass Filter Set, suitable from f/15 to f/1.8 – with 2" (M48) filter thread
- 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 planeoptically 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
- Mounted in Baader Low Profile Filter Cell (LPFC) – 6 mm height
This new generation of Baader CMOS-filters features:
CMOS-optimized Baader Filters
- 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™: ever-harder coatings to enable a non-aging coating for life, even in the most adverse environment
