Color Sensitivity
The effects of object reflectivity on cutoff distance, though small, may be important for some applications. It is expected that at any given cutoff setting, the actual cutoff
distance for lower reflectance targets is slightly shorter than for higher reflectance targets. This behavior is known as color sensitivity.
For example, an excess gain of 1 for an object that reflects 1/10 as much light as the 90% white card is represented by the horizontal graph line at excess gain = 10. An
object of this reflectivity results in a far limit cutoff of approximately 130 mm (5.1 in); thus 130 mm represents the cutoff for this sensor and target.
These excess gain curves were generated using a white test card of 90% reflectance. Objects with reflectivity of less than 90% reflect less light back to the sensor, and thus
require proportionately more excess gain in order to be sensed with the same reliability as more reflective objects. When sensing an object of very low reflectivity, it may be
especially important to sense it at or near the distance of maximum excess gain.
