The compact optoNCDT 1420LL laser sensors from Micro-Epsilon, Ortenburg, Germany, perform precise distance measurements on metallic and structured surfaces. The sensor projects a small laser line onto the measuring object, which compensates for any interference. This ensures stable and reliable measurement values. These sensors are used whenever standard laser point sensors reach their limit. Working with a small laser line rather than a laser point enables the sensors to measure accurately even on rough, diffuse, and shiny metallic surfaces. The laser line ensures optical averaging and compensates for irregular surfaces. The sensors achieve reliable, highly precise measurement values on rough surfaces, as well as defects, recesses, and holes and are available with measuring ranges of 10, 25, and 50 mm.
