Baader UBVRI Bessel I-Filter – Photometric
Highlights
- Baader UBVRI-I Band-pass Filter, suitable from f/15 to f/1.8
- Classic photometric filter with transmission according to Bessel – Par focal with all Baader filters of the same size
- Manufactured with most advanced ion beam coating technology / Daylight-Proof
- 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
- Equally suitable for modern CMOS cameras as well as for older CCD camera technologies
This new generation of Baader Filters features:
CMOS-optimierte Baader Filter
- 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
