Measurement 5Reflective 2D Laser Displacement Sensor

Thickness is found by simultaneously measuring the base surface and target using a 2D laser displacement sensor and measuring step from the obtained profile.


Errors occur when there is a gap between the target and the reference surface.

  • 1. Use a base surface with high precision, such as a surface plate.
  • 2. Use vacuum contact or magnetic contact.

Improving mounting using the above steps will significantly improve measurement accuracy.
