Displacement sensors with a blue laser

Micro-Epsilon presents at first a triangulation sensor that utilise Blue Laser technology. In numerous applications, Blue Laser sensors are superior to standard sensors that use a red laser diode. When measuring on metals, particularly annealing metals and organic materials such as wood, skin, foodstuffs, veneers, etc., the wavelength of the blue-purple laser offers significant benefits. In contrast to a red laser, the reduced wavelength of the blue laser light does not penetrate the measuring object. The blue laser generates a minimal laser point on the surface and therefore offers stable, precise results on measuring objects that are normally considered as critical. The design of triangulation sensors with Blue Laser technology is a complete re-design. The sensors are equipped with new high-end lenses, new intelligent laser control and evaluation algorithms. Laser sensors with Blue Laser illustrate the ongoing development of numerous standard commercially available laser sensors.

For example, the optoNCDT 1700 industrial standard laser sensor provides this new Blue Laser technology. Depending on the measuring object and measuring range, the appropriate sensor can be selected with either red or blue laser light.
