Baader H-Beta 5.5nm 31 mm CMOS optimized Narrowband Baader H-Beta Filters
This new generation of Baader CMOS filters features:
- CMOS-optimized Baader filters
- Increased contrast
- Narrower and narrower pass bands
- Reflex-Blocker ™ coatings, for the greatest freedom from halos, even in the most adverse conditions related to auxiliary optics
- FWHM in each filter category carefully designed to allow 1: 1: 1: 1 exposures, combined for typical CMOS quantum efficiency and s/w ratio
- Filter thickness identical to existing standards, with extreme care for parafocality
- Blackened edges all around, with filter lead-side indicator in the form of a black outer edge on the front side, to additionally eliminate any reflections due to light falling on the edge of a filter
- Each filter individually coated, with sealed coating edge (NOT cut from a larger plate with exposed coatings)
- Life-Coat ™: increasingly harder coatings to allow for a coating that will not age for life, even in the harshest environment
Summary key features:
- 31 mm x 2 mm Baader H-Beta narrow band filters - Precision grade
- FWHM of 5.5 nm, recommended for f/10 to f/3.5 optical systems
- 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 outer edge on the front side
- Optimized for modern CMOS cameras, but excellent for CCD camera technologies
