Micro-Epsilon optoNCDT 2300-2DR blue laser sensor

The Micro-Epsilon optoNCDT 2300-2DR blue laser sensor is specially designed for displacement and distance measurements on directly reflecting surfaces. The compact sensor operates at high speeds on these surfaces and provides maximum precision in the nanometre range.

It can be used for thickness measurements of flat glass, distance measurements on annealed glass and assembly monitoring of extremely small parts. The measuring rate can be set up to 49 kHz, making the sensor suitable for process monitoring tasks. While operating with advanced real-time surface compensation (A-RTSC), the sensor enables a precise real-time surface compensation of different surface types. Data output is via Ethernet, RS422 or EtherCAT.

The sensor is designed for a parallel installation to the measured object. The blue laser light is directly reflected onto the receiving optics by the measured object and, unlike red laser light, the blue laser light does not penetrate the object. A sharp point is projected onto the surface, which enables a stable signal on the receiver element— achieving nanometre resolution. In addition, the extremely small laser spot size allows the sensor to detect very small objects.
