Laser Profiler Models

This topic introduces different laser profiler models, as well as the characteristics and suitable applications of each model.

Comparison of Key Specifications

The currently available models of the sensor head of the laser profiler include:

  • LNX-8000 series: LNX-8030, LNX-8080 and LNX-8300 (used with the LNX-8000C controller)

  • LNX-7500 series: LNX-7530, LNX-7580 and LNX-75300 (used with the LNX-7500C controller)

The following table provides the comparison of key specifications of the sensor head models. For all technical specifications of the laser profiler, please refer to LNX-7500 Series and LNX-8000 Series.
