Vai al moduloThe Baader L-RGB Filter Set CMOS-Optimized 36mm (Luminance / Red / Green / Blue) is the combination of four anti-reflection filters in unmounted format, designed for color imaging with monochrome CMOS cameras and the most common filter wheels, with extremely high transmission on each color channel.
Four filters, one balanced exposure
The set includes a Luminance filter (UV/IR cut, 98% transmission across the entire visible spectrum 420-685nm) and the three RGB filters (Red 595-690nm, Green 490-580nm, Blue 400-510nm). The balanced design allows the same exposure time to be used for each subframe — crucial for automated imaging sequences — while reducing stray light and reflections to an unprecedented level.
Baader CMOS-Optimized technology
Each filter is coated with Reflex-Blocker™ treatment, which eliminates unwanted reflections even in the presence of auxiliary optics, and with Life-Coat™ technology: a hardened coating that does not peel, degrade, and lasts the entire life of the filter even in the most extreme conditions. The edges are blackened all around, with a visual indicator on the front side for correct orientation during mounting. Each filter is individually polished and coated, with no exposed coating edges.
