Abstract

The invention discloses an electric lens cover of a large-aperture telescope, which belongs to the technical field of photoelectric equipment and comprises an upper lens cover assembly, a lower lens cover assembly, a telescope front cover and a window protection assembly. An upper lens cover assembly and a lower lens cover assembly are fixedly installed on the side wall of the telescope front cover. And a window protection assembly is arranged at the port of the telescope front cover. The electric lens cover provided by the invention can solve the dustproof problem of the electric lens cover of a large-aperture telescope in an open state and a closed state, reduces the variable quantity of the rotational inertia of the telescope along a pitch axis when the electric lens cover is opened and closed, and can be opened and closed manually.

Description

technical field [0001] The invention belongs to the technical field of photoelectric equipment, and in particular relates to a motorized lens cover suitable for large-diameter telescopes. Background technique [0002] High-power laser large-aperture telescopes are used in air defense, terminal anti-missile, and blinding of airborne photoelectric equipment. They are used to quickly track and strike targets. By irradiating laser light on the locked part of the target, the target can be quickly burned. High-power lasers are very sensitive to dust and dust. If there is dust attached to the surface of the protective window of the telescope, the high-power laser will quickly destroy the coating layer on the surface of the protective window. If it is light, the output laser power will be reduced to affect the striking effect, and if it is serious, it will damage the telescope. There may even be safety incidents. Therefore, for the electric lens cover of the protection window of th...
