Laser sensors for metals and rough surfaces optoNCDT LLSensors with small laser line (LL) for rough and reflecting surfaces optoNCDT LLSensors with small laser line (LL) for rough and reflecting surfaces When measuring on shiny metals or machined surfaces that have small micro-machining marks on their surface, using a small laser spot is not recommended. This is because the micro-machined surface features suppress homogenous reflections, resulting in a noisy or unstable measurement signal. Laser sensors with an oval-shaped laser spot of just a few mm in width, similar to a short ‘laser line’, are recommended for these tasks. Interference caused by surface roughness, defects, indentations or holes are filtered out using the oval-shaped light spot combined with special software algorithms. Furthermore, this type of sensor is suitable for distance measurements on structured surfaces i.e. when the distance to the surface and not the structure itself needs to be measured. The oval-shaped light spot is not affected by the surface structures, enabling continuous, stable measurement values to be generated. Anti speckle laser sensor – optoNCDT 1700LL The optoNCDT 1700 LL is a special laser sensor for shiny metals and structured surfaces. The oval laser spot facilitates a particularly easy and precise measurement on shiny metal surfaces or structured objects.

Due to this laser line, the optoNCDT 2300LL is also very well suited for precise distance and displacement measurement on glossy, porous or rough surfaces. Due to the high measurement rate of up to 49kHz it is possible to reliably apply the sensor in fast processes. The parameterization of the laser sensor is effected via web interface which is contacted via the Ethernet interface. Via the web interface numerous possibilities for the measurement value and signal processing are offered.
