Optical rotating bench

Abstract

The invention discloses an optical rotary table, which is formed by a driving source, a roller lead screw, a nut, a sliding block, a guide plate, a connecting rod, a middle post, a bearing, a plate, a base, a roller sheath, a rolling guide rail, a tension spring, a read block and a pointer. Wherein, said optical rotary table is left and right symmetry; the connecting rod, plate, roller guide rail, roller, roller sheath, read block and point are both distributed one group at the left and right of symmetry line. The invention has simple structure and easy installment, while two groups of optical elements rotate coaxially in reversed directions synchronously and the rotate angle difference can be accurately adjusted.

Description

technical field [0001] The invention relates to an optical rotary table, in particular to an optical rotary table suitable for two groups of optical components to rotate synchronously and reversely around a common axis, and the rotation angle difference can be adjusted in a small amount. Background technique [0002] The optical rotary table is a common adjustment device for adjusting the angle of optical components in optical experiments and optical instruments. The optical components are fixed on the platen of the optical turntable, and their angles can be adjusted by the rotation of the optical turntable. [0003] The prior art [1] (the Newport Resource, Motion Control: Manual Rotation Stages and Motorized Rotation Stages. 2003, P.969-1032) describes various models of one-dimensional optical rotation stages. These one-dimensional optical turntables are widely used because of their individuality and diversity, meeting many requirements for use. But a one-dimensional opti...
