Method of assembling a curved prism

This invention relates to prism assembly and calibration technology. To address the problems of low assembly efficiency and inability to guarantee assembly accuracy in existing curved prisms, a method for aligning curved prisms is proposed. First, based on the relationship between the curved prism and the optical system, the position coordinates of the two theoretical sphere centers of the curved prism are calculated. Then, the position coordinates of the two sphere centers are located using a coordinate measuring system, and target balls are placed at the corresponding position coordinates of the two theoretical sphere centers. A first centering instrument and a second centering instrument are used to align the target balls at the position coordinates of the two theoretical sphere centers, and then the first and second centering instruments are fixed. The target balls at the position coordinates of the two theoretical sphere centers are removed, and the curved prism is installed into the optical system. The curved prism is adjusted, and the two actual sphere centers on the curved prism are observed through the first and second centering instruments until the two actual sphere centers coincide with the two theoretical sphere centers, thus completing the assembly and calibration of the curved prism.
