The optoNCDT 1900LL sensors by Micro Epsilon are designed for distance measurement on metallic and structured surfaces in measuring ranges of 10 and 25mm. A special cylindrical lens expands the light spot to an oval light spot. Optical averaging over the oval light spot compensates for surface unevenness. In addition, the signal is optimized by algorithms. The sensors are particularly advantageous for measurement tasks with pure distance changes in the Z-direction. For movements in the X- or Y-direction, they also provide more stable measured values than comparable point sensors.
In the combination of resolution and speed, the 3D sensors of the C6-3070 series by AT Automation Technology impress with the new WARP technology (Widely Advanced Rapid Profiling).
