Interference reduced

Rather than using a spherical or point-shaped laser spot, the new optoNCDT 2300LL sensor uses a unique laser line and special software algorithms to filter out any interference caused by very small (sub-micrometre) surface defects on shiny objects such as polished metals, mild steel and rubber.

The sensor 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 patented software algorithms, so that any interference caused by surface roughness, defects, indentations or holes down in the sub-micrometre range – are dramatically reduced.
