DEVICE FOR HIGH-PRECISION POSITIONING OF APEX OF SECONDARY MIRROR, WHICH IS DISPLACED WITH RESPECT TO APEX OF TELESCOPE PRIMARY MIRROR; AND TELESCOPE

摘要

FIELD: optical instruments. SUBSTANCE: secondary mirror is mounted on support using linking members. Said linking members comprise first and second extended radial and crossing linking members which run on both sides of support along first X-X direction and along second Y-Y direction through center of support, corresponding to apex of said secondary mirror. In addition said first and second linking members are rigid in longitudinal direction, and each linking member is mounted for controlled movement along its axis using corresponding driving members. EFFECT: possibility of active correction of possible disturbance of required respective position of two apexes of displaced primary and secondary telescope mirrors. 10 cl, 3 dwgd
