Optical Profilometer - White-Light/Phase-Shift Interference (Filmetrics Profilm3D)
The Filmetrics Profilm3D is an optical profilometer, using White-Light Interferometry (WLI) and/or Phase-Shift Interference (PSI) imaging through microscope objectives, to produce a 3D image of the sample.
Technique & Capabilities
White-Light Interferometry (WLI) provides an optical measurement similar to a Confocal Microscope, although using white light instead of a single color.
Phase-Shift Interference (PSI) enables sub-nm surface topography for nominally "flat" samples (ie. no step heights), enabling AFM types of measurements with no surface contact and in much less time. Surface curvature of a few-mm area can also be obtained.
