EVEREST Soft X-ray / XUV / VUV Spectrograph

Our XUV / VUV spectrograph features aberration-corrected flat-field imaging and is available with three gratings covering the spectral ranges 117 nm (124073 eV), 580 nm (24815.5 eV) and 24200 nm (51.76.2 eV). In order to maximize light collection, the spectrometer can be used without an entrance slit over a variety of source distances, with 317 nm, 1080 nm and 24200 nm spectral coverage. Its modular design is able to match different experimental geometries and configurations. It features an integrated slit holder, gate valve and filter insertion unit, as well as motorized grating positioning along 3 axes.
