Lens-Less sensor

The Lens-less sensor is a fixed field of view DHM®, this unique patented design is robust and ideal for industrial applications.  The reflection configuration measures 3D topography with a sub-nanometric resolution.

Digital holography offers significant advantages compare to other 3D optical profilometers:

  • Fast measurement
  • Insensitive to surrounding vibrations
  • Digital focalization : doesn’t require mechanical displacement
  • The laser wavelength is the height reference: no drawbacks from scanning mechanisms

Ideal for automation

  • Compact design for easy integration
  • Camera outside of the main body for easy maintenance
  • External laser source for easy integration and maintenance
