AbstractTo determine parameters of the Segmented Mirror Telescope is quite essential for the design, manufacture, testing and construct of the telescope system, especially the F-number parameters and curvature radius of the primary mirror, as well as the asphericity. A model of Sub-segmented mirror was established in this paper, based on which, using the feature points combined with lagrange condition extreme, the asphericity calculation of the asymmetrical hexagon off-axis parabolic mirror in different central points is solved. The 8m and 11m segmented mirror telescope were taken for example in the calculation, and got the relation curve between F-number of primary mirror and Asphericity of segmented mirror, respectively. This work is useful for the design, manufacturing and testing of the large diameter Segmented Mirror Telescope. © 2014 SPIE.; To determine parameters of the Segmented Mirror Telescope is quite essential for the design, manufacture, testing and construct of the telescope system, especially the F-number parameters and curvature radius of the primary mirror, as well as the asphericity.
