DEVICE FOR FIXING MIRROR OF TELESCOPE Russian patent published in 2019 - IPC G02B7/183 

FIELD: optics.

SUBSTANCE: invention relates to optical instrument making. Device for fixing the telescope mirror comprises a base and three supports arranged uniformly along the circumference of the base. Supports are attached to the base by means of support brackets fixed by means of bolts-axes installed with tight fit of surfaces of support brackets and surface of the base. Supports are made in the form of oscillating arm, which are plates. At both ends of arms there fixed are tie-rods made in form of flat rods with cylindrical part-pancake at inner ends, connecting arms with mirror, when outer ends of rods are rigidly connected with arms, and inner ends of rods are glued in special recesses in end face of mirror. Arms are attached to the base by means of elastic bearings made of two identical halves, between which the arm is fixed. Each of the bearing halves is formed by a rigid centre and periphery interconnected by thin-walled flat plates - elastic lobes, due to elastic deformation of which the centre of the bearing can be rotated relative to the periphery. Ring is installed on the outer side of the mirror and is connected to the base. On the ring there are three tangential supports consisting of bracket with a ball-shaped finger. In the mirror there are special cavities in which the embedded bushings are glued, made cylindrical with flat inner walls. On back side of mirror there made is finning of special configuration, designed with special cells arranged evenly along ribbing circumference, intended for installation of tie-rods in them in form of flat rods with cylindrical part-pancake at inner ends. Number of mirror finning cells is equal to the number of tie-rods, and they are arranged so that each tie-rod is installed into the corresponding finning cell of the mirror.

EFFECT: technical result consists in minimization of structural elements with uncontrolled backlashes, as well as elimination of additional mirror unloading at ground adjustment of telescope.
