The principle of all types of spectrometers and structural features are studied , a new metrhod to design prism spectrometer system with wide field of view is proposed ,which is based on the offner struture .This type of spectrometer allows twice dispersion through the same prism.Compared with the traditional dispersive spectrometer system ,which can be greater dispersion width and smaller volume.Compared with the gating spectrometer ,which overcomes low diffracion efficiency,spectrum overlapping, ghosts, low SIR and other shortcomings. Finally, the design results were analyzed, and the image quality was evaluated.The results from the design anslysis showed the spectrometer has a smaller spectrum bending ,the MTF of the system at different wavelengths is close to the diffraction limit and the design meets the requirements .
