Abstract

A simple but very efficient device for micro-Raman spectroscopy of highly absorbing solid samples is described. The device allows rapid scanning of the focused laser beam on the surface of a solid sample, which avoids heating of the sample. By means of a pair of computer-controlled piezo-translators, which are fixed to the microscope objective, the laser beam can be scanned in a great variety of traces, the scattered light of which is collected and optically transformed into a very small spot at the entrance slit of the spectrometer. The system is tested on highly absorbing (partially) polymerized diacetylene single crystals at low temperatures.
