Abstract In the experiment of adjusting and applying a spectromeler, it involves adjusting the Ielescope,
stage,and collimator ,which is relatively complex for beginners,When students see abnoral grating diffractionpattems or seemingly normal but with significant measurement errors, they ofien camnot identify the keyreasons,mainly dae to their insuflieient understanding of the relevant optical principles,During the adjustmentoroeess,they iust mechanically follow the operation steps in the textbook. Based on the above, this papercomprcherninglh amahboaed the imdiuence of varioe pnate gf the spretromcter on the ertingtiffation fringer,students to comprehend the experimental principles and determine the
adjustment state of the spectrometer bydistribyution of diffraction fringes ,so as to complete the experiment with high quality.
