CMOS Optimized RGB-B Filter - 47.4mm

The Baader CMOS Optimized RGB-B Filter is an anti-reflection blue bandpass filter with extremely high transmission of the blue color channel, optimized for modern CMOS cameras while also performing excellently with CCD camera technologies. With a balanced RGB design, it allows subframes to be taken with the same exposure time—critical for automated imaging tasks—with the FWHM carefully designed for 1:1:1 exposures matched to typical CMOS quantum efficiency and signal-to-noise ratio. This 47.4mm unmounted blue filter is especially selected for use with 2" filter sliders of the Baader FCCT (Filter Changer Camera Tilter) for RASA 8 and QHY cameras. The Baader Life-Coat™ technology provides durable coatings that resist moisture, temperature extremes, and are hardened to withstand normal cleanings.
