Chemical Imaging Using NIR, IR, and Raman Spectroscopy

A second combination of two techniques provides a solution to the problem of obtaining the Raman spectrum from a rough surface. On rough or inclined samples, a high level of con-focality can cause part of the scanned area to be out of focus. This is especially true for larger 

The scanned area was 2x2 mm with a maximum topographic range in the scanned area of approximately 1.3 mm. If such an area is scanned in confocal Raman imaging mode without
