In order to make the Wollaston prisms get better transmitting performance,the influence of the refractive index of optical cement used in Wollaston prisms on the splitting ratio and the transmission was analyzed in this paper.The relationship formula about the refractive index of optical cement and the splitting ratio and the transmission was worked out,and besides,the relationship curves were fitted by computer.The result indicates that the refractive index of optical cement used in Wollaston prisms can influence both the splitting ratio and the transmission;and especially when the value of the splitting ratio is 1 and the value of total transmission reaches the maximum,the value of refractive index of optical cement is the same.If the wavelength of the light is 633nm,the value of the index is 1.570.The result is very helpful for optimizing the transmitting performance of Wollaston prisms.
