| Abstract: | Based on the previous work, a modified model of adjustment mechanism of the imaging lens's focal length of a space solar telescope is designed. Analysis on the environment and contact ifluence of the modified model are also presented in the paper. The design principle is illustrated in the article. The movement of the image lens is controlled by the step motor and screw. According to the result of the contact analysis, the modified mechanism is workable. |
