"High Performance Double-Confocal Micro-Raman System and Applications"

Friday, November 9, 2018  
at 3:30 pm in CB 4058

Abstract:  This is a report on the development of a high-brightness confocal micro-Raman system assembled from components found in most optics labs or readily available from various suppliers.  An assembly approach can reduce system cost significantly if the major components are already at hand.

Further, we show how a second confocal pinhole and two in-line Rayleigh rejection filters can improve overall signal-to-noise and low wavenumber signal recovery, with only minimal reduction in throughput to the detector.

Finally, we demonstrate the system performance using a series of `straight-forward' and `more challenging' sample types.
