Baader UV IR Cut filter CMOS optimized 2" M48

Baader UV IR Cut filter CMOS optimized 2" M48

DESCRIPTION
This new generation Baader UV IR Cut filter is optimized for modern CMOS sensors. Supplied in a 2" mounted version with M48 thread, it easily fits most standard focusers and accessories.

With a passband of 420–685 nm and 98% transmission in the visible range, the filter effectively blocks unwanted UV and IR radiation, preventing star bloating and improving sharpness, especially in red-sensitive sensors.

Reflex-Blocker and Life-Coat technologies reduce halos and ensure long-lasting durability, even under harsh environmental conditions or repeated cleanings. Each filter is individually coated, with blackened edges and a telescope-side indicator for correct orientation.

Compatible with fast optics (from f/15 down to f/1.8), the filter supports well-balanced RGB exposures and is parfocal with other Baader filters thanks to its standard thickness.
