Trace gases, as important constituents of the atmosphere, play an important role in the ecology of the planet. In order to realize the requirements of, wide-band, hyperspectral and all-weather continuous measurement, a hyperspectral imaging spectrometer operating in occultation detection mode is designed in this paper. The system is a dual-channel structure with a common slit, the UV-visible channel adopts a single concave grating, and the infrared channel adopts a structure combining Littrow and immersion grating, which effectively reduces the volume. The software was used to optimize the optical structure, and the optimization results showed that the spectrometer operated in the range of 250−952 nm wavelengths, of which the UV-visible channel operated in the wavelength range of 250−675 nm, the spectral resolution was better than 1 nm, the MTFs were all higher than 0.58 at a Nyquist frequency of 20 lp/mm, and the RMS values at various wavelengths of the full-field-of-view were all less than 21 μm; the infrared channel operates in the wavelength band of 756−952 nm, the spectral resolution is better than 0.2 nm, the MTF is higher than 0.76 at the Nyquist frequency of 20 lp/mm, and the RMS value at each wavelength in the whole field of view is less than 6 μm, all of them meet the design requirements. It can be seen that the hyperspectral imaging spectrometer system can realize the occultation detection of trace gases.
