This 47.4mm Round, Unmounted Baader CMOS-Optimized UV/IR Bandpass L Filter from Alpine Astronomical reflects harmful thermal radiation in the infrared spectral range and provides 98% transmission over the entire visible spectrum from 420-685nm. It also prevents blurred star imaging with red-sensitive digital and CCD/CMOS cameras. It 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. This filter is designed for use with the Baader FCCT for RASA 8 astrograph.

UV/IR Cut: 420-685nm    Optimized for CMOS, Suitable for CCD    Reflex-Blocker Hard Coated    Life-Coat Sealed Coating Edges

• Reflex-Blocker coatings offer largest ever freedom from halos, even under most adverse conditions concerning aux-optics
• Provides increased contrast
• Identical filter thickness to existing standards (2mm), with utmost care for parfocality
• FWHM on each filter category carefully designed to allow for 1:1:1 exposures, matched for typical CMOS quantum efficiency and S/N ratio
• 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 from a larger plate with coatings left exposed)
• Life-Coat evermore hard coatings enable a non-aging coating for life, even in the most adverse environments
