31 mm diameter Baader UV/IR-Cut / L filter optimized for CMOS
This new generation of Baader CMOS filters features:
- CMOS-optimized Baader filters
- higher contrast, combined with typical CMOS quantum efficiency and s/w ratio
- Reflex-Blocker™ coatings, for the greatest freedom from halos, even in the most adverse conditions related to auxiliary optics
- 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 telescope 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 hard coatings to allow for a coating that will not age for life, even in the harshest environment
General Features:
- 31 mm x 2 mm Baader UV/IR-Cut bandpass filter (420 - 685 nm), suitable from f/15 to f/1.8
- Reflects harmful thermal radiation in the infrared spectral range
- Provides 98% transmission over the entire visible spectrum from 420 to 685 nm
- Avoids blurred star images with digital cameras and red-sensitive CCD/CMOS
- Hard-coated and planoptically polished Reflex-Blocker™ with sealed coating edges (Life-Coat™)
- Blackened edges all around, with filter lead side indicator in the form of black outer edge on the telescope side
- Optimized for modern CMOS cameras, but excellent for CCD camera technologies
