Digital Holographic Microscopy

Digital Holographic Microscopy

Digital Holographic Microscopy (DHM®) offers solutions for static and dynamic 3D characterization in material science and life science applications.

Reflection DHM®

Reflection DHM® measures the reflected wavefront from the sample, i.e. the surface topography in case of purely reflecting sample.

DHM® is more than a standard optical profilometer as it enables dynamic measurement within vertical ranges from nanometers to hundreds of microns with sub-nanometric vertical resolution.

Applications:

  • Surface topography
  • Surface finish
  • Defect inspection
  • Structured thin film
  • MEMS measurement

Transmission DHM®

Transmission DHM® measures the optical path difference of a beam travelling through samples .

For measurements of micro-optical components, microfluidic devices, and defects or particles inside transparent samples, Transmission DHM® systems are usually the optimal choice.

In biological imaging the pioneer users of DHM® have demonstrated through seminal publications the interpretation of DHM® measurements in terms of underlying biological processes.

Transmission DHM® systems are the best choice for fast non-perturbing measurements.
