Short Answer
Yes, Roll-2-Roll® Sensors detect clear films using infrared light reflection without recalibration.
Yes. Roll-2-Roll® Sensors detect clear films using infrared light reflection. Even transparent materials reflect a small amount of infrared light, which the sensors CMOS line camera and adaptive algorithms can reliably detect. This is a key advantage over ultrasonic sensors, which cannot reliably detect clear films, and traditional infrared sensors that require recalibration for different transparency levels.
