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.
