Sažetak
In a microscope of a micro-Raman spectrometer a cylindrical lens is introduced to form a line-focus microprobe (LFMP). The dimensions of the LFMP are 0.66 x 167 Pm. The lateral spatial resolution of Raman scattering with the LFMP is equal to the spatial resolution of the point-focus microprobe (PFMP). It is shown that the LFMP system enables measurements with a laser power density that is 320 times lower than the PFMP. For the same laser power density in both types of illumination, the LFMP Raman spectra give approximately +/i or 18 times better signal-to-noise ratio. Key words: Micro-Raman spectroscopy, cylindrical lens, microscopy, spectroscopic techniques.
