Abstract	The H alpha imaging spectrograph (HIS) is the scientific payload of the first solar space mission, the Chinese H alpha solar explorer (CHASE), supported by the China National Space Administration (CNSA). The CHASE/HIS achieves, for the first time in space, H alpha spectroscopic observations with high spectral and temporal resolutions. Separate channels for the raster scanning mode (RSM) and continuum imaging mode (CIM) are integrated into one, and a highly integrated design is achieved through multiple folding of the optical path and ultra-light miniaturized components. The design of HIS implements a number of key technologies such as high-precision scanning of the optical field of view (FOV), high-precision integrated manufacturing inspection, a large-tolerance pre-filter window, and full-link solar radiation calibration. The HIS instrument has a pixel spectral resolution of 0.024 A and can complete a full-Sun scanning within 46 s.
