3D Optical Profilometry

Optical profilometry is a non-contact metrology technique for surface topography characterization. The technique provides 2D and 3D images of a surface as well as numerous surface texture parameters such as Ra-, Sa- and Sz-values.

Typical measurements include:

  • Surface roughness
  • Step height/depth
  • Dimensions
  • 3D imaging
