Solar telescope guider taking optical wedge as refractive element

Abstract

The invention relates to a solar telescope guider taking optical wedges as refractive elements. A video CCD (Charge Coupled Device) is arranged on a guider lens barrel or a main lens barrel. The solar telescope guider is characterized in that four optical wedges are arranged in front of a guided objective lens and are same in angle and shape; the installation positions of the four optical wedges are as follows: the four optical wedges are uniformly distributed at an angle of 90 degrees around the center shaft of the guided objective lens; the mutual directions of the four optical wedges are as follows: the four optical wedges are respectively arranged at angles of 90 degrees; and the parameters of the four optical wedges are as follows: optical wedge angles alpha are 32-40 arc minutes, light deflection angles beta are 16-20 arc minutes, and the glass refractive index n is 1.4-1.6. According to the invention, the defects of low accuracy, low anti-interference capability or high cost or more complex objective lens cutting and deflecting assembly, and the like in the prior art are overcome; and lens surface cutting is prevented in such a way that a solar image is deflected by utilizing the refraction of the optical wedges, so that great convenience for assembly and debugging is achieved. The solar telescope guider disclosed by the invention has the advantages of simple structure, easiness for manufacture and assembly and convenience for batch production.

Description

technical field [0001] The invention belongs to the field of opto-mechanical-electrical equipment, and in particular relates to a solar telescope guide mirror with an optical wedge as a refraction element. Background technique [0002] The solar telescope is an astronomical telescope dedicated to observing the sun. During long-term observation, due to factors such as optics, machinery, electrical appliances and meteorology, the image of the sun will gradually deviate from the initial position. In order to solve this problem, a telescope is generally used Install a smaller guide lens tube on the frame, use the sun image in the guide mirror to guide manually or automatically by computer, that is, manually or computer recognizes the deviation of the sun image of the guide star, and controls the motor micro If the deviation is eliminated, the guide star image remains unchanged. Since the guide star lens barrel is fixedly installed on the main lens barrel, and the length and we...
