Compact mechanism for universal adjustment of coude reflecting mirror

Abstract

The invention relates to a universal adjustment mechanism for a compact coude reflecting mirror, which comprises a rotary adjusting component, a translational adjusting component and a mounting component. The mounting component comprises a steering plate, a mounting shaft and a connection head, the mounting shaft is fixed at the center of the steering plate and is overlapped with the optical axis of the main reflecting mirror, the connection head is fixed at the other end of the mounting shaft, the other end of the steering plate is fixedly connected with the back plate of the coude mirror, and the geometric center of the steering plate and the optical center of the coude reflecting mirror are on the same straight line. The technical problem of time and labor consumption of the adjusting method for the existing coude reflecting mirror is solved, a compact reflecting mirror adjustment mechanism with the function of universal adjustment is provided, gaskets are eliminated, and repeated repair research is avoided. Moreover, the coude reflecting mirror needs not to be removed, and the precise positioning of the reflecting mirror can be completed only via simple adjustment.

Description

technical field [0001] The invention belongs to the field of reflector adjustment, and in particular relates to a compact universal adjustment folding axis reflector mechanism. Background technique [0002] Large aperture and long focal length collimator is the key equipment for debugging and testing of large focal length optical remote sensing cameras, and its performance directly affects the joint debugging of camera subsystems, the progress of testing work and the accuracy of testing results. Therefore, ensuring the imaging quality and improving the stability of the optical performance are the primary tasks of the structural design of the large aperture and long focal length collimator. Generally, the total size of the collimator with large aperture and long focal length is very long. The main performance indicators of the collimator are: focal length f: 20M; clear aperture D: Φ600mm; centerline obscuration b: ≤ Φ100mm. The optical system combining the X magnification gr...
