The TrueSurface Microscopy System from Witec
Dr. Olaf Hollricher from Witec
shows us their award winning TrueSurface Microscopy system. It uses
Raman spectroscopy technology but has advantages over confocal Raman
spectroscopy in that it is able to accurately track the surface of the
sample and in the process keeping it in focus at all times. This allows
it to produce accurate Raman spectra at all points across the surface.
The demonstration illustrates how it can be used across a curved
surface, but the system is equally capable on rough or corrugated
Furthermore, the TrueSurface Microscopy system can collect
Raman spectra at all points across the surface producing chemical maps
across the surface as well as topographical maps of the sample surface.
Run time - 5:05 minutes.
