Short-wave infrared hyperspectral camera of transmission-type grating

The utility model relates to the technical field of cameras, and discloses a transmission-type grating shortwave infrared hyperspectral camera, which comprises a lens, a bayonet diaphragm, a slit component, a collimating lens, a transmission grating, a focus lens and a detector which are fixedly connected in sequence, and one end of a cable assembly is electrically connected with the detector; the optical axis of the lens, the optical axis of the bayonet diaphragm, the optical axis of the slit component, the optical axis of the collimating lens and the optical axis of the transmission grating are located on the same straight line. The optical axis of the transmission grating and the optical axis of the focus lens are arranged at an angle of 22 +/-2 degrees; the focus lens is used for converging a one-dimensional space image of the near-infrared band monochromatic light of the visible light to a light-sensitive surface of the detector, and the detector is used for processing light intensity information of the
