The invention discloses a hyperspectral camera, a spectrograph and a manufacturing method thereof. The hyperspectral camera comprises at least two camera units, wherein each camera unit comprises an optical lens, a light uniformizing column, a multi-band optical filter and an image sensor which are arranged in sequence, and the optical lens is used for acquiring spectral information of a measured object; the light uniformizing column is used for uniformly distributing spectral information of the measured object on the multi-band optical filter; the multi-band optical filter is used for splitting the spectrum of the measured object, and the multi-band optical filter is formed by splicing a plurality of single-band optical filters; and the image sensor is used for receiving spectral energy of the measured object. According to the implementation of the invention, a plurality of camera units comprising multi-band filters are combined, and each filter corresponds to a plurality of camera sensor pixels, so that the
