Generating confocal images becomes faster，easier andmore flexible， from the deep UV to the IR. The Raman microscope has become a powerful analyticaltool for many applications including pharmaceuticals，polymers， semiconductors， forensics and life science.The new generation of Raman microscopes offers a non-destructive and non-contact method of sample analysis atthe micron level. More particularly， Raman imaging providesthe spatial distribution of the various molecular species withina heterogeneous sample， making it possible to produce fastand accurate 1 mm) obtained in macro-mapping mode. The colorscorrespond to the integrated intensity of the Si band (red)and of the respective G bands of the CNTs (green and blue). Once the CNT of interest has been located， a high-definitionimage ofthe CNT is then obtained by zooming in with DuoScanTMin step-by-step micro-mapping mode (inset). In that case， theapparent width of the CNT (366nm) is a convolution of the tubediameter with the laser spot size. This shows the superior spatialresolution achievable with a confocal microscope.

In this example， a17.5 mm by 7 mm pellet was analyzed. As the DuoScanTMautomatically matches the image pixel size to the scannedarea， the full surface is covered， ensuring no spot is missed. As with the previous example， step-by-step mapping can. be performed on a region of interest to look at finer details(Figure 6).
