New high speed laser for displacement measurement of reflective surfaces

Bestech has unveiled the new optoNCDT 2300-2DR blue laser sensor specially designed for displacement and distance measurements on directly reflecting surfaces.

This compact sensor operates at high speeds on these surfaces and provides maximum precision in the nanometer 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 49kHz which is why the sensor is ideally suitable for process monitoring tasks.

While operating with the 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 based on a parallel installation to the measurement object. The blue laser light is directly reflected onto the receiving optics by the measurement object. Unlike red laser light, the blue laser light does not penetrate the measurement object.

A sharp point is projected onto the surface, which enables a stable signal on the receiver element – achieving nanometer resolution.

Also, the extremely small laser spot size allows the sensor to detect very small objects.
