Blue Laser sensors

The optoNCDT BL models are equipped with a blue laser diode and are used when standard sensors with a red laser diode are operating at their performance limits. Due to its shorter wavelength, the blue laser does not penetrate the target surface, projecting a small light spot on the surface and therefore providing stable and precise results. As Blue Laser sensors are equipped with a special filter, they are insensitive to highly emitting objects such as glowing metals. Blue Laser sensors are preferably used with measurements on organic and (semi-)transparent objects, as well as for red-hot glowing metals.

New: High Precision Blue Laser Displacement Sensor

The optoNCDT2300-2DR is the new model in the high performance optoNCDT 2300 range. The beam path is designed for direct reflection and will find applications in the measurement of high-gloss, shiny and reflecting surfaces. Blue Laser technology from Micro-Epsilon and its optical arrangement result in a laser sensor that is extremely sensitive to changes in distance, which enables very high measurement accuracies. The new model is used in consumer electronics production (e.g. smartphones, tablets and displays), industrial applications and for the production and processing of semiconductors.

Patented Blue Laser Technology

Measurement tasks involving blue laser sensors on red-hot glowing objects exceeding 700 °C and transparent objects such as plastics, adhesives and glass are patented by Micro-Epsilon. The optoNCDT Blue Laser models achieve excellent signal stability and thus precise measurement results on these surfaces.
