Request Information
optoNCDT 1900 LL laser sensors are designed for the measurement of shiny metallic and rough surfaces. Their small laser line enables precise measurement results with shiny metallic surfaces and structured objects. Due to their extremely compact size, the sensors can also be integrated into restricted installation spaces.

Characteristics

 N/A
  • Precise laser sensor with oval-shaped light spot (laser line)
  • For shiny metallic, rough and structured surfaces
  • Unique combination of compact size, high speed and accuracy
  • Ideal for static and dynamic measurements with high resolution
  • Highest ambient light resistance in its class
  • Advanced Surface Compensation for high speed measurements on changing surfaces

Additional Information

N/A The optoNCDT LL laser sensors produce an oval-shaped light spot of just a few millimeters 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.

Laser sensors with oval-shaped light spot (laser line)

The optoNCDT 1900LL is the latest Micro-Epsilon laser sensor. This innovative sensor projects an oval-shaped light spot which reminds of a short laser line (LL). The laser sensor impresses with precise distance measurements on shiny metallic and structured surfaces, as well as materials where the laser beam penetrates. The integrated high-performance controller enables fast and highly precise processing and output of measurement values. The innovative optoNCDT 1900LL laser triangulation sensor is used wherever high precision and reliability are required, e.g., in challenging automation tasks, automotive production, 3D printing and in measuring machines.

Advanced Surface Compensation The intelligent exposure control for demanding surfaces

The optoNCDT 1900LL is equipped with an intelligent surface control feature. New algorithms generate stable measurement results even on demanding surfaces where changing reflections occur. In addition, the sensor has the highest resistance to ambient light in its class and can be used in strongly illuminated environments up to 50,000 lux.
