Sensors with small laser line (LL) for
rough and reflecting surfaces

The optoNCDT LL laser sensors produce an oval-shaped light spot of just a few millimetres in width which reminds of a short »laser line« (LL). This oval light spot compensates for inhomogeneous surface structures and the so-called »speckling« effect which particularly occurs with metallic surfaces. Combined with special software algorithms, interferences caused by surface roughness, defects, indentations or holes are filtered out. This enables stable and precise measurement results.

Reliable measurements on structured and metallic surfaces

The optoNCDT LL laser sensors operate with an oval-shaped light spot which reminds of a small laser line. They are used for static and dynamic distance measurements on rough and structured surfaces, on metals and measuring objects where the laser penetrates the material.

The optoNCDT LL laser sensors are available in several series with different measuring ranges, measuring rates and accuracies. They are used for precise distance measurements on structured surfaces, i.e. when the distance to the surface and not the structure itself needs to be measured. For fine details and surface structures, the optoNCDT sensors with a point-shaped laser and the Blue Laser sensors are the preferred choice.

Klapper_optoNCDT-2300-LL_Laserline_500x250
Laser sensors from the optoNCDT 2300LL series have been developed with an innovative lens arrangement which produces and elongated elliptical spot (or small laser line). Although not visible to the naked eye, this change in the spot geometry allows a natural surface averaging. Combined with an advanced surface compensation algorithm, this combination dramatically reduces measurement signal noise levels, especially on shiny, glossy, porous or rough surfaces.

Compared to a conventional standard laser spot, this measuring stability is dramatically improved, even when measuring at the extreme high rate of 49kHz!

Additionally, the optoNCDT 2300LL has the new Ethernet interface which is used for remote configuration, diagnostics (through the devices own IP address) and output measurements. Conventional serial RS422 and analogue outputs are also offered if preferred.
