Foreground suppression is used with targets having shiny or irregular surfaces. The sensor’s low black/white error of 10% ensures reliable detection regardless of the target’s color or glossiness. Visible beam allows easy alignment, while the sensor’s algorithm minimizes the effect of external light interference from fluorescent lighting.
