  • Interferometric Microscopes
    Interferometric microscopes use the interference patterns of light waves for precise determinations of distance, thickness, surface or step heights, wavelength, roughness and non-contact 3D surface profiles. As in conventional interferometers, measurements are made by analyzing the phase shift

    tolerances. This plays an important part in view of the subject EMC (electromagnetic compatibility), which is also essential for hema. To protect the electronics of the microscope built into the case from high frequency electromagnetic radiation interference and to avoid emissions, a closed shield
  • Surface Profiling by Frequency Domain Analysis of White Light Interferograms

  • What is Frequency Domain Analysis?
    shifting interferometry (PSI), which allows us to transform the interference pattern electronically into a matrix of phase values. These phase values can then be directly related to relative height values, provided that the wavelength or optical frequency of the source light is known
  • Adaptive wavefront correction in two-photon microscopy using coherence-gated wavefront sensing
    from individual scatterers. Interference effects between those waves cancel, except for extremely high or inhomogeneous densities of scatterers (M.R. and W.D., unpublished data). Because each scatterer acts as an independent source of a spherical wave, CGWS should thus not depend on the incoming
