High precision measurement on metallic surfaces

02/02/2021

The new optoNCDT 1900LL uses a special cylindrical lens which expands the conventional point of light to an oval-shaped light spot. This laser sensor is designed for stable distance measurements on structured and metallic surfaces. Optical averaging via the oval light spot compensates for unevenness of the surface. In addition, the signal is optimized via intelligent software algorithms. This increases the signal stability particularly on shiny metallic, rough and structured surfaces.

The laser line reveals its major strength with measurement tasks that involve a pure distance change in the Z-axis. With movements in the X- or Y-axes, the measurement values are more stable than those from comparable point sensors.

The combination of compact size, high speed and accuracy is a unique character of optoNCDT 1900 laser sensors. Similar to the standard models, the LL series has a high measuring rate, offers unsurpassed resistance to ambient light and is equipped with the extremely fast »Advanced Surface Compensation« exposure control feature. The optoNCDT LL models are available with measuring ranges of 10 mm and 25 mm.
