| 英文摘要 | The curvature radius error in the Seya-Namioka grating process can cause defocus aberration, which may have a great impact on the spectral performance of the grating monochromator. Based on the theory of ray tracing, we simulate and analyze the impact of curvature radius error on Seya-Namioka grating. The analysis results show that the length of the entrance and exit arm has a good compensating effect on the curvature radius error. By adjusting the length of the entrance and exit arm, the allowable range of the curvature radius error can be increased to about 2 mm. If the total adjustment amount is not changed and the length of the access arm is arbitrarily changed, the compensation effect is similar. As the error increases, the length of the arm that needs to be adjusted becomes larger, and the excessive error makes the length of the arm unable to be compensated. In addition, changing the angle between the arm and the arm can only compensate for the error of the positive curvature radius. The adjustment angle needed for compensation is too large, which will affect the design structure of the monochromator, and it is not practical to compensate the curvature radius error by changing the angle of the entrance and exit arm. The research results in this paper show that by adjusting the parameters of the grating, the influence of errors can be reduced and the margin of error can be extended. 2018, China Science Publishing & Media LTD.
