This 49mm 695/092 IR Dark Red MRC Basic Filter from B+W is a moderate strength infrared filter that does not block the complete visible light spectrum, enabling image recording with visible and invisible IR components. The black and white contrasts are not as high as those produced by black-red IR filters.
The filter is made of precision German optical glass, each side featuring 7 layers of Broadband coating for high contrast pictures with minimal residual reflection and uniform light transmission. The brass filter ring features an enhanced knurling pattern for improved grip and a special functional coating for smooth mounting and dismounting. The ring features front threads, and its low-profile design makes it suitable for use with wide-angle lenses.
