    In order to investigate the influence of the optical elements of Czerny-Turner (CT) optical path structure on the optical properties of the spectrometer when the optical elements are deviated from the theoretical design parameters, the mathematical model was established to successfully restore the asymmetric CT optical path structure designed by Zemax, under the condition of unaffecting the spectrometer resolution, the components of adjustable redundancy was got. The results show that the adjustable range of the deflection angle of the collimating mirror and the diffraction grating is ±0.19 and ±0.17 degrees, and the adjustable range of the condenser and the CCD is ±0.12 mm. The adjustable range of the above four variables is the smallest, which has a great influence on the final resolution of the spectrometer. The research provides the references for the mechanical adjustment mechanism of each optical element in CT structure.
