UNAVAILABLE - Optical Profilometer - White-Light/Phase-Shift Interference (Filmetrics Profilm3D)
|
THIS TOOL HAS BEEN REMOVED FROM THE LAB AND IS UNAVAILABLE as of 2019. Please see the Olympus LEXT Confocal Microscope for similar capabilities.
About
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.
