Photometric Filter Ø 1¼" BESSEL UBVRI-U Baader Planetarium

1¼" DIAMETER PHOTOMETRIC FILTER BESSEL UBVRI-U 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

• 1¼" x 2 mm Baader Bessel-UBVRI-U bandpass filter, suitable from f/15 to f/1.8 - with 1¼ "(28.5 mm) filter thread
