B+W 092 49mm MRC Infrared Filter

The B+W 092 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.
