Our XUV / VUV spectrograph features aberration-corrected flat-field wavelength coverage from 1nm to 200nm. Wide-band spectral measurements are possible by three gratings covering 1-20nm, 5-80nm, and 40-200nm. The spectrometer can be used without entrance slit to maximize light collection for a range of source distances. Its modular design is able to match different experimental geometries and configurations. It features an integrated slit holder and filter insertion unit, as well as a motorized grating positioning. Characteristics: Flat-field grazing-incidence spectrograph Wavelength ranges: XUV coverage from 5 to 80 nm with a single grating, optional SXR wavelength range 1 to 20 nm. VUV version coverage 40 to 200 nm Large selection of geometry options Flexible choice of detectors: x-ray CCD-camera or MCP/fiber taper system Operating pressure <10-6 mbar Oil-free pump system for stand-alone vacuum operation optionally available Customizable according to user requirements Wavelength [nm] 1-10 3-20 5-40 10-60 25-80 40-200 Operation mode slit-less slit-less slit-less slit-less slit-less slit-less Source distance [m] flexible flexible flexible flexible flexible flexible Flat-field size [mm] 35 45 21 50 50 100 Dispersion [nm/mm] 0.2 – 0.35 0.3 – 0.4 0.5 – 0.65 0.7 – 1.1 0.9 – 1.3 ≈ 2.0 Resolution [nm] < 0.03 < 0.035 < 0.06 < 0.09 < 0.11 < 0.15 * Other configurations (spectral range, slit operation, high-resolution, etc) available upon request. Customization： Every spectrometer is customized to exactly match the desired application,e.g. Interfacing to experimental chambers Adaption of the source distance Integration of customer-supplied detectors User-defined filter mounts
