OVERVIEW
IR Black Red 830 (093)
The B+W 093 infrared filter blocks the entire light spectrum. It therefore appears almost black and captures the pure IR range without visible red. It enables image results with extreme contrasts.
PLEASE NOTE
Infrared photography is not a substitute for a thermal imaging camera. The pictorial infrared photography described above is often confused with thermal photography. This also forms images from infrared radiation, but in a much higher range (from about 10,000 nm and above)
