These new sensors with BlueLight technology enable optimum detection in even more applications:

  • reliable detection of reflective surfaces even at wide angles, e.g. varnished wooden surfaces, coated metal and painted plastic parts
  • detection of transparent objects without use of a reflector, e.g. film, Petri dishes and cannulae
  • detection of very dark objects, e.g. solar wafers, foam and plastic
