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.
Reliable measurements on structured and metallic surfaces
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.
Interface and signal processing units
The compact optoNCDT 1420 LL laser sensors are designed for measurements of shiny metallic and rough surfaces. The oval light spot, which resembles a short laser line, can better compensate for unevenness such as texture and roughness. Special software algorithms filter out interference caused by surface roughness, defects, depressions or the smallest holes.

Instead of a common laser point, optoNCDT 2300LL laser sensors project a very small laser line onto the target surface. This laser line makes the optoNCDT 2300LL particularly suitable for precise displacement and distance measurements both on shiny, porous and rough surfaces. The high measuring rate up to 49 kHz enables reliable measurements in high speed processes. Parameter setting of the laser sensor is via a web interface that is addressed via an Ethernet interface. This web interface offers many features for the evaluation and processing of measured values and signals.
