Foundation sealing inflatable solar telescope

Abstract

The invention provides a foundation sealing inflatable solar telescope, comprising main sealing window glass (1), a lens cone inflation port (2), a lens cone (3), a thermal diagram liquid inlet pipe (4-1), a primary mirror (5), a centerpart (6), an air distribution box (7), an air inlet pipe (8-1), a primary mirror back cover (9), a sealing thermal insulation layer (10), a lens cone exhaust port (11), a thermal diagram liquid outlet pipe (4-2), a thermal diagram (12), a gas state monitoring module (13) and a secondary mirror (14). The foundation sealing inflatable solar telescope provided by the invention adopts a closed lens cone to effectively protect optical devices; an inert gas is filled to significantly reduce the difference of inner and outer pressures of the lens cone; and the mirror surface thermal deformation and the local seeing effect are minimized by thermal control. The foundation sealing inflatable solar telescope provided by the invention has the advantages of effectively protecting the optical devices, having no significant difference of inner and outer pressures of the lens cone, having no significant thermal effect, being easy to maintain, and the like, is obviously superior to the existing solar telescope scheme, and has high innovativeness and practicability.

Description

Technical field [0001] The invention relates to the field of astronomical observation instruments and equipment, in particular to a ground-based sealed inflatable solar telescope. Background technique [0002] Solar imaging observation data is the most basic observation data for solar physics research and solar activity forecasting, and the most important equipment for obtaining solar imaging observation data is the ground-based solar telescope. According to the diffraction limit formula, the larger the aperture of the optical system, the higher the resolution. Therefore, in order to obtain smaller-scale solar activity information, the aperture of ground-based solar telescopes is increasing. [0003] Before 2000, most solar telescopes were less than 1 meter in diameter. In order to protect the optical components, the telescope mostly adopts a closed structure. At the same time, in order to further eliminate the thermal deformation of the mirror surface and the local seeing effect...
