The left chart shows the adjusted detection distance compared to the actual sensing distance for white, gray, and black objects using a BGS sensor with a visible red light source. At an adjusted distance of 700mm, the measured sensing distance varies by ~150mm depending on what color is present. The right chart shows the same for a BGS sensor with an infrared source. This results in a sensing distance variation by color that can be just one third that of visible red versions, at the same distance.
