【Abstract】 While recording spectra by using the WPL miniature prism spectrograph,the image distance of violet light is longer than that of red light.In this paper,ZEMAX,an optical calculation software,was used to calculate the optical parameters of each component in the optical path of the prism spectrograph.Calculation results and detailed analysis of longer violet image distance in the prism spectrograph were also given numerically and accurately by using the calculation formula of optical system.更多还原
