Abstract

Disclosed is a multifunctional astronomical telescope integrating a sun observation function with a star observation function. A Gregore optical system is employed as a basis of a three-mirror system. The multifunctional astronomical telescope is characterized in that the optical system is internally provided with a coude reflector for transiting light reflected by a primary mirror and a secondary mirror to an altitude axis, and system focal ratio conversion is carried out through a flat spherical mirror on the altitude axis; three focuses are designed for a system: a main focus is provided with a view field diaphragm, a reflector and a refrigeration apparatus and is shared with a star observation optical path; a system focus provided with a magnetic analyzer calibrating apparatus; and a scientific focus which involves whole-reflector imaging; and a conversion apparatus is arranged at the focus position of the main mirror, and through switching between the view field diaphragm and an image field correction mirror, switching between a sun observation optical path and a star observation optical path is realized. The multifunctional astronomical telescope provided by the invention solves the problem that sun observation and star observation cannot be realized in the one astronomical telescope in the prior art, and realizes unification of wide spectrum, large view field, high-quality imaging and high-resolution spectrum measuring functions under the condition of sun and star observation.

Description

technical field [0001] The invention relates to a multifunctional astronomical telescope integrating the functions of solar observation and star observation, and belongs to the field of optical system design. This invention is funded by the 2.5-meter multifunctional telescope development project and the National Natural Science Foundation of China (11273040). Background technique [0002] Observation of the sun and observation of stars and galaxies are the main contents of astronomical research, and scientists have a great demand for both types of telescopes. After continuous exploration, people have summed up some general-purpose telescope optical systems, which are suitable for astronomical observation in several fields. The system is widely used in solar observation. The primary mirror focus of the Gregorian system can be used to install field diaphragms and reflectors, which can not only effectively reduce the influence of heat on imaging, but also meet the requirements...
