Baader LRGB 2" Filter Set – CMOS Optimized

Baader LRGB 2" Filter Set – CMOS Optimized

DESCRIPTION
The Baader 2" LRGB filter set is tailored for use with modern CMOS sensors. It includes red, green, and blue passband filters, plus a luminance filter (UV/IR cut) transmitting 98% from 420 to 685 nm. The RGB filters feature extremely high transmission in their color channels while efficiently blocking unwanted light and reflections. Each filter is finely plano-optically polished and sealed with hard Reflex-Blocker™ coatings (Life-Coat™). The spectral design allows identical exposure times across all channels—ideal for fully automated imaging sessions. Filters are mounted in low-profile LPFC 6 mm cells, with blackened edges and telescope-facing markings to suppress lateral light reflections.
