Contrast Sensors

Cont­rast sen­sors de­tect the fi­nest cont­rast dif­fe­ren­ces on a wide range of ma­te­ri­als and sur­fa­ces. Print marks can be de­tec­ted aga­inst any backg­ro­und, re­gard­less of bright­ness or color va­lu­es, and ob­jects can be de­tec­ted based on their cont­rast dif­fe­ren­ces. Hig­hest cont­rast re­so­lu­ti­ons are ge­ne­ra­ted by long-​life white light LED or red laser light.
