WebJan 1, 2010 · An optical profiler produces a detailed three-dimensional (3-D) surface map of a test area with Angstrom-level height resolution that can be further analyzed according to … WebOptical profilometry is a rapid, nondestructive, and noncontact surface metrology technique. An optical profiler is a type of microscope in which light from a lamp is split into two paths by a beam splitter. One path directs the light onto the surface under test, the other path directs the light to a reference mirror.

WebDue to the opacity of these systems, Raman analysis is restricted either to exterior surfaces or cross sections. As Raman spectra are only recorded from one focal plane at a time, the sample is usually altered to create a smooth and even surface. However, this manipulation can lead to misinterpretation of the analytical results. http://www.nuance.northwestern.edu/keck-ii/index.html tsuutina health center
