Laser displacement sensor for lustrous surfaces

Pinterest LinkedIn Tumblr

Micro-Epsilon has developed a new highly dynamic laser sensor for displacement measurements of lustrous metal, coarse, and textured surfaces. In contrast to point-type laser models, the measuring point is extended to form a line which helps prevent interferences during measuring.

Coarse surfaces cause interferences for laser points and make displacement measurements on metal more difficult. The new series of high-end optoNCDT 2300 LaserLine (LL) laser sensors circumvents this problem. Special lenses extend the laser point to a short line. A particular algorithm is used to calculate the average value across the length of the line. Any interferences are filtered out efficiently, and the distance to the metal can be determined accurately.

For now, the new series includes four models with measuring ranges between 2 and 50mm. The maximum measuring rate is 49.02 kHz (adjustable). optoNCDT 2300LL provides a resolution of up to 0.03 µm and a linearity of up to ± 0.6 µm. The new Advanced Realtime Surface Compensation (A-RTSC) hardware has been developed based on established RTSC technology. The dynamic range of arrays and precision of real-time surface compensation during the measuring process have been improved compared to previous models. The sensor with its integrated controller has a compact footprint of just 80 x 75 mm. Data output is via Ethernet, EtherCAT, or RS422. Easy sensor configuration via the web interface.
