The OptoNCDT 2300LL non-contact laser line displacement sensor from Micro-Epsilon is designed for the high-speed measurement of shiny metallic and rapidly changing, rough or other difficult-to-measure surfaces. An ideal application for the sensor is said to be structured surfaces where the distance to the surface and not the structure itself needs to be measured.

The sensor — which measures 80 x 75 x 30mm in size — uses a laser line and software algorithms to filter our any interference caused by sub-micrometre surface defects on shiny objects such as polished metals, mild steel and rubber.

It uses a special cylindrical lens that widens the laser spot to an oval shape. Although this shape appears as oval to the human eye, the actual shape is a very small line. Measurements using this laser line are then averaged using Micro-Epsilon’s software algorithms so that any interference caused by surface roughness, defects, indentations or holes are dramatically reduced.

The OptoNCDT 2300LL uses Advanced Real-Time Surface Compensation (A-RTSC) technology, which enables the sensor to automatically compensate in real time for difficult-to-measure surfaces.
