Baader has released the New CMOS-Optimized filters. Please contact us for further info.
- Baader H-alpha / O-III / S-II Narrowband Filter Set - Precision Grade
- 6.5 nm FWHM, recommended for optical systems from f / 10 to f / 3.5
- 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 frontside outer rim
- Optimized for modern CMOS cameras, but excellent for CCD camera technologies
The new generation of Baader CMOS-optimized filters features:
- CMOS-Optimized Baader Filter
- Increased contrast
- Ever more narrow passbands
- Reflex-Blocker™ coatings, for largest ever freedom from halos, even under most adverse conditions concerning aux-optics
- FWHM on each filter category carefully designed to allow for 1:1:1 exposures, matched for typical CMOS quantum efficiency and s/n ratio
- 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 black frontside 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
