Support structure and primary mirror telescope unit

摘要

A support structure of primary mirror supporting a primary mirror (1) so that the rotational structure EL (2) including two members arcuate (2a) facing each other and each has an outer surface slide along a sliding surface arranged on the side face of a cylinder around the axis rotates the primary mirror (1) about the axis, characterized by comprising: - an entangled structure forming a frame (6) extends between the two arcuate members (2a), under the primary mirror (1) and connected to the arcuate members (2a) at the ends; and - a support structure (7) primary mirror includes multiple support members (7a, 7b), connecting each of the multiple support members (7a, 7b) a point or multiple points on the circumference of the primary mirror ( 1) the frame structure (6) and causing the frame lattice structure (6) bear the weight itself of the primary mirror to support the primary mirror (1), wherein at least the support members (7b) closest to Member arcuate (2a) are connected to the frame lattice structure (6) in parts (6a) different end where the frame framework structure (6) is connected to members arcuate (2a ), so that the load of the primary mirror (1) supported by the support members (7b) closest members arcuate (2a) is not applied directly to members arched (2), and the weight of the primary mirror itself is endured by shaped members arc (2a) through the support members (7a, 7b) and the frame lattice structure (6) thereby reducing the difference of sinking between the center of the surface of primary mirror and sides of the surface of primary mirror .
