  • Compact wideband VUV spectrometer
    Patent number: 10753798
    Abstract: The invention relates to a compact wideband vacuum ultraviolet (VUV) and soft X-ray grazing incidence spectrometer based on a plane amplitude diffraction grating. The spectrometer enables simultaneous detection of a VUV spectrum in a positive first order of diffraction and a negative first order of diffraction. The technical result of the invention is that of recording a spectrum in a wide spectral range (3-200 nm) with a moderate spectral resolution (?/??˜15-30) and with a significantly higher spectral resolution (?/??˜100-200) in a narrow soft X-ray or extreme ultraviolet range with the possibility of measuring the absolute radiation output in these regions of the spectrum.
