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.
