Photometric Filter Ø 2" BESSEL UBVRI-V Baader Planetarium

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
