Retro-Reflex Sensors for Transparent Objects

Where con­ven­tio­nal retro-​reflex sen­sors reach their li­mits, the retro-​reflex sen­sors for trans­pa­rent ob­jects en­su­re that ex­tre­me­ly shiny ob­jects like glass, PET bot­t­les, trays or film can be de­tec­ted. By using single-​lens op­tics wit­hout a blind spot, retro-​reflex sen­sors can de­tect ob­jects through small ope­nings like holes or gaps.
