2" DIAMETER PHOTOMETRIC FILTER BESSEL UBVRI-V BAADER PLANETARIUM
- 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 indicator on the filter cable side 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
TECHNICAL FEATURES
- 2" x 2 mm Baader Bessel-UBVRI-V bandpass filter, suitable from f/15 to f/1.8 - with 2" filter thread (M48)
- Classic photometric filter with transmission according to Bessel - parfocal with all Baader filters of the same size
- Manufactured with the most advanced ion beam coating / daylight-proof technology
- 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 telescope side
