Our sensors are based on light intensity shadow measurements and employ LED sources instead of lasers. Since they have no moving parts, they are more reliable, require lower maintenance and have longer lifetime: click DEMONSTRATION

Compared to conventional fault or flaw detectors, our PROFILE SENSORS allow the detection and characterization of smaller defects on wires and filaments running at higher speeds and with superior precision.

To build our sensors compact and robust, we take advantage of Swiss tradition in fine mechanics and micro technology combined with the use of advanced miniaturized optoelectronics components commercially available from modern optical telecommunications systems.
