Considerations when evaluating a Near Infrared camera

Recent growth in the automotive and security industries has increased the number of cameras designed for viewing both Near Infrared (NIR) and visible wavelengths of light. NIR illumination is invisible to the human eye and can light a dark scene without being visible or annoying. Because silicon sensors are sensitive out to 1100 nm — well beyond NIR wavelengths of interest — existing consumer systems require only a small modification, the removal of the infrared filter, to allow them to image NIR. This makes dual-band security cameras cost-effective and attractive to the industry. (more…)
