| 摘要 |
The invention relates to a measuring device (1, 41, 51) for recording a Raman spectrum, comprising a measurement cell (3) having a number of penetration windows (5), at least one light source (9, 61, 63) disposed outside of the measurement cell (3), a detector (13) disposed at an angle a to the light source (9, 61, 63) and a focal optic (21) for imaging the or every light source (9, 61, 63) at a focal point (23, 71), wherein the focal optic (21) is located within the measurement cell (3). The measuring device (1, 41, 51) comprises reflectors (20, 27, 43) that can be implemented as retro reflectors. Furthermore, a plurality of light sources (9, 61, 63) can be coupled into the measurement cell (3). This allows for the rapid and precise investigation of fluid samples using a thermally and mechanically stable measuring device. |
