| 摘要 |
The invention relates to a device (122) having an arrangement of optical elements, comprising excitation light sources (101, 115) for producing individual light beams (102, 116) having different wavelengths for exciting a sample in such a way that light scattered back by the sample as a result of the excitation is made available to a Raman spectroscopic analysis. The device (122) comprises deflecting devices (103, 117) associated with the individual light beams (102, 116) for deflecting the individual light beams (102, 116) onto a common light path, wherein the common light path comprises a common optical system (109) for focusing the light beams (102, 116). |
