Abstract

A dual-axis multi-optical channel switching device suitable for large solar telescopes, consisting of a radial adjustment seat 1, an inclination adjustment seat 2, a bracket 3, a field of view diaphragm 4, a vertical rotation axis motor 5, an axial adjustment seat 6, Double-channel rotating shaft 7, polarization device 8, driving worm gear pair 9, horizontal rotation motor 10, positioning switch 11, connecting plate 43, circular partition 12, locking screw 42, adjusting screw 13, adjusting screw 31, adjusting screw 41 compositions. A dual-axis multi-optical channel switching device invented for large-scale solar telescopes can realize fast switching and precise positioning of polarizing devices or other optical devices through computer control; it can realize different sizes of field of view diaphragms or other Fast switching and precise positioning of the device; a five-dimensional manual adjustment mechanism is set, which can accurately adjust the positions of the polarizing device and the light barrier and lock them firmly; the structure is compact, and there is no obstruction to the optical path.

Description

technical field [0001] The invention relates to the field of structural design of astronomical telescopes, in particular to the support and switching structure design of a polarization device and a field of view diaphragm at the focal point of a large solar telescope F2. Background technique [0002] Large-scale solar telescopes are generally equipped with multiple focal points for arranging different functional components, such as the thermal field of view diaphragm at the main focus F1; the Gregorian focal point F2 with magnetic analysis instruments and the second field of view diaphragm; the folding axis focus F3 is equipped with various scientific instruments. [0003] For the magnetic analysis instrument arranged in front of F2, it is necessary to have the function of moving in and out of the optical path, so as to avoid frequent removal and replacement of the magnetic analysis instrument when the telescope switches between magnetic field measurement and other observati...

AI Technical Summary

Problems solved by technology

[0004] The Gregorian focus F2 is located in the center of the lens barrel, and its front end needs to be arranged with two components, the magnetic analysis instrument and the second field of view diaphragm. At present, there are technical problems to be solved: 1) The two components need a support mechanism, the support mechanism Need to have full degree of freedom adjustment and locking function; 2) Magnetic analysis instrument needs to switch structure to realize cutting in and out; 3) The second field of view diaphragm also needs to switch mechanism to realize switching between different sizes of diaphragm; 4) Support mechanism and switching The structure requires high precision and is limited by the size of the space; 5) the support and switching mechanism itself and the parts are not allowed to block the optical path in the cut-out position
