Description

Highlights

  • Baader UBVRI-I Bandpass Filter, suitable from f/15 to f/1.8
  • Classic photometric filter with transmission according to Bessel – parfocal with all Baader filters of the same size
  • Manufactured with most advanced ion beam coating technology / Daylight-Proof
  • Reflex-Blocker™ hard coated and planeoptically 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 parfocality
  • 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
