A coma-free super-high resolution optical spectrometer using 44 high dispersion sub-gratings
Abstract Unlike the single grating Czerny–Turner configuration spectrometers, a super-high spectral resolution optical spectrometer with zero coma aberration is first experimentally demonstrated by using a compound integrated diffraction grating module consisting of 44 high dispersion sub-gratings a...
