Alpine Astronomical Baader SLOAN/SDSS ugriz' Filterset (1.25" Eyepiece Filter)

This , from Alpine Astronomical, includes all six (u', g', r', i', z-s', and y') SLOAN/SDSS bandpass filters.

Alpine Astronomical Baader SLOAN/SDSS u' Filter (1.25" Eyepiece Filter)

This 1.25" Eyepiece Filter Baader SLOAN/SDSS u' Filter, from Alpine Astronomical, is part of the ugriz' bandpass filter set, is suitable for use from f/15 to f/8, and is a photometric filter offering transmission performance according to SLOAN specifications. This daylight-proof filter uses ion-beam coating technology and features a Reflex-Blocker hard coating, which has been planeoptically polished, and has Life-Coat sealed coating edges. It is equally suitable for modern CMOS sensors as well as for older CCD camera technologies.

• Reflex-Blocker coatings offer largest ever freedom from halos, even under most adverse conditions concerning aux-optics
• Identical filter thickness to existing standards (2mm), with utmost care for parfocality
• Blackened edges all around, with filter-lead-side-indicator in the form of a black frontside 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)
• Life-Coat: evermore hard coatings to enable a non-aging coating for life - even in a most adverse environment
