| 摘要 |
This invention concerns a transmission Raman spectroscopy apparatus comprising a light source (101) for generating a light profile (110) on a sample (102), a photodetector (103) having at least one photodetector element (103a), collection optics (104) arranged to collect Raman scattered light transmitted through the sample (102) and direct the Raman light onto the at least one photodetector element (103a) and a support (109) for supporting the sample (102). The support (102) and light source (101) are arranged such that the light profile (110) can be moved relative to the sample (102) in order that the at least one photodetector element (103 a) receives Raman scattered light generated for different locations of the light profile (110) on the sample (102). |
