Brand: 
Lyncée Tec
Category: 
Digital Holographic Microscopy (DHM®)

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 others 3D optical profilometer :

  • 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
