BAADER UV/IR-CUT & CMOS L-FILTER Size:50.4mm The flattener features high qualityThe Baader UV IR cut CMOS optimized Luminance filter is a photographic filter designed to reject the ultraviolet and infrared ends of the spectrum, where telescope optics are not typically corrected. The transmission is 98% over the entire visible spectrum between 420 685nm. This is an essential accessory for CMOS cameras which do not have a built in IR cut coating on the sensor glass. The optical surface is fine optically polished with Reflex Blocker
