Beam paths of the MS3 microspectrophotometer. All optical axes converge at two beamsplitters underneath the reflective Schwarzschild microscope objective. From there they are deflected on-axis with the X-ray beam by a drilled 45° mirror behind the objective. The imaging branch of the sample-viewing microscope is split by a further beamsplitter into a low-magnification and a high-magnification fixed-zoom branch with separate firewire CCD cameras (Point Grey GRAS-20S4-C). The spectroscopic unit contains the beamsplitter separating the excitation from the detection branch, both coupled via light fibers to various lasers and the spectrographs, respectively. |
