A full-absorption ideal field of view diaphragm device suitable for symmetrical optical path solar telescopes

Abstract

The invention discloses a full-absorption ideal field-of-view diaphragm device suitable for a solar telescope with a symmetrical optical path, so as to realize the full absorption of light energy in the field of view in a limited space, and overcome the object quality of stray light, vignetting, etc. unfavorable factors. The device of the present invention specifically includes an inner layer heat-absorbing refrigeration device and an outer layer heat-absorbing refrigeration device, wherein the inner layer heat-absorbing refrigeration device specifically includes a reflective light bar liquid inlet channel 1, a reflective light bar liquid outlet channel 2, a light bar support 5, a guide bar The flow cover 6 and the reflecting light barrier 7; the outer layer heat-absorbing refrigeration device specifically includes the liquid inlet channel 3 of the extinction tube, the liquid outlet channel 4 of the extinction tube and the extinction tube 8 . By adopting the technical solution of the present invention, the advantages of no vignetting of the follow-up focal plane image, no stray light entering the effective field of view, good thermal uniformity of the optical path, and the like can be brought.

Description

technical field [0001] The invention relates to the field of solar telescope thermal field of view diaphragm structure design, in particular to an ideal thermal field of view diaphragm device suitable for segmental full absorption without stray light and vignetting for large-aperture symmetrical optical path solar telescopes. Background technique [0002] As a normal main sequence star in the universe, the evolution and development of the sun is not much different from other similar stars. However, from the perspective of the relationship between the earth and the sun, the periodic changes in solar activity and sudden solar activity will have a greater impact on the earth and other planets in the solar system, and then have a decisive impact on the evolution of the earth's surface ecosystem Impact. In order to carry out early warning and forecast of solar activity so as to avoid the influence of "disastrous space weather" on human activities to the greatest extent, it is ne...
