Abstract
In this paper,the refractive index of visible light in the triple prism was measured by the methord of minimum deviation.Based on the expirical foumula of Cauchy,the experimental data was investigated in Origin software,and the dispersion curvers of the triple prism were obtained.The parameters A0 and B0 of the ZF1 optical glass and the K9 optical glass were determined and the angular diapersion power of two optical glass were obtained.The experimental results show that the angular dispersion power of triple prism related to not only prism materials but also the wave length of the incident light.The angular dispersion power increases with the increase of refraction index and increases with the decrease of wave length.
