Cognex · 3D Vision Systems

Compact, factory-calibrated 3D laser sensor series with blue laser technology, up to 4,000 3D points and sub-0.5 µm vertical resolution.

The L68 series are laser displacement sensors for high-speed, high-resolution 3D inspection, measurement and guidance. Blue laser technology delivers up to 4,000 3D points and vertical resolution below 0.5 µm.

Each sensor is calibrated individually at the factory against reference points across its field of view and measuring range, correcting perspective, lens and laser deviations. The sensors run with VisionPro software, and the compact housing simplifies machine and robot integration.

Key features

  • Blue laser; up to 4,000 3D points, vertical resolution below 0.5 µm
  • Factory calibration for measurements in real-world units
  • Integrated optics and laser illumination
  • AI and rule-based 3D tools in VisionPro
  • Quadrature encoder input (RS-422); compact IP67 housing

Applications
