Laser sensors for metals and rough surfaces
The optoNCDT LL laser sensors produce an oval-shaped light spot of just a few millimeters in width which reminds of a short "laser line" (LL). This oval light spot compensates for inhomogeneous surface structures and the so-called "speckling" effect which particularly occurs with metallic surfaces. Combined with special software algorithms, interferences caused by surface roughness, defects, indentations or holes are filtered out. This enables stable and precise measurement results.
The optoNCDT LL laser sensors are available in several series with different measuring ranges, measuring rates and accuracies. They are used for precise distance measurements on structured surfaces, i.e. when the distance to the surface and not the structure itself needs to be measured. For fine details and surface structures, the optoNCDT sensors with a point-shaped laser and the Blue Laser sensors are the preferred choice.
