Description

Technical field

[0001] The invention relates to the technical field of thermal field diaphragm temperature control of solar telescopes, in particular to a thermal field diaphragm temperature control device that can be used for large-aperture ground-based solar telescopes. Background technique

[0002] With the deepening of solar physics research, the scientific community's demand for high-resolution observation of solar active regions is becoming increasingly urgent, and at the same time, solar telescopes continue to develop in the direction of large apertures. Compared with space-based solar telescopes, ground-based solar telescopes have become an important direction for the development of solar telescopes because of their relatively low cost, easy maintenance, and multiple payloads. Divided by aperture, ground-based solar telescopes with an effective aperture of meter-level and above can be called large-aperture ground-based solar telescopes. While the large-aperture solar tel...
