B+W F-Pro 092 Infrared Filter deep-purple red 695 52

B+W 092 Infrared filter 695, 52 mm

The B+W 092 IR filter 695 looks almost black, but is deep purple-red in front of a light source. It blocks visible light up to 650 nm, and at just below 700 nm it allows 50% to pass through (hence the dark red color). From 730 nm to 2.000 nm the transmittance is very high at over 90%. This allows shots of the pure red and IR image. This IR filter is suitable for most digital cameras.
