A device for precisely positioning the focus of a telescope

Abstract

The invention discloses a focal point accurate positioning device for a telescope, and belongs to the field of optical instruments. The focal point accurate positioning device for the telescope comprises a panel, a laser, a first total reflector, a second total reflector, a third total reflector, a fourth total reflector, a first semi-reflecting and semi-transparent mirror, a second semi-reflecting and semi-transparent mirror, a third semi-reflecting and semi-transparent mirror and a fourth semi-reflecting and semi-transparent mirror, wherein the first total reflector, the second total reflector, the third total reflector, the fourth total reflector, the first semi-reflecting and semi-transparent mirror, the second semi-reflecting and semi-transparent mirror, the third semi-reflecting and semi-transparent mirror and the fourth semi-reflecting and semi-transparent mirror are arranged on the panel; the panel is parallel to the horizontal plane; the laser is positioned on one side of the table; and the laser and the panel are positioned on the same horizontal plane. The focal point accurate positioning device for the telescope is simple in structure, convenient to operate and wide in applicability; and the position of the focal point of the telescope can be quickly and accurately positioned; the working time is saved; and the working efficiency is improved.

Description

[0001] Technical field: [0002] The invention relates to a device for precisely positioning the focus of a telescope, which belongs to the field of optical instruments. [0003] Background technique: [0004] The application of telescope is more and more extensive, more and more popular. In the application of the telescope, the precise positioning of the telescope focus is very important, especially in the tiny energy detection technology, the telescope usually plays the role of concentrating light. [0005] If the focus position of the telescope cannot be precisely positioned, the energy focused by the telescope cannot be fully received, which affects the detection efficiency of the telescope. There are many methods for locating the focus of the telescope in the prior art, most of which locate the focus of the telescope according to the optical parameters provided by the telescope manufacturer; Not wide. Another commonly used method is to use moonlight to locate the focus ...

Problems solved by technology

[0005]If the focus position of the telescope cannot be precisely positioned, the energy focused by the telescope cannot be fully accepted, which will affect the efficiency of the telescope detection

There are many methods for locating the focus of the telescope in the prior art, most of which locate the focus of the telescope according to the optical parameters provided by the telescope manufacturer; not wide

Another commonly used method is to use moonlight to locate the focus of the telescope, but the focus position determined by this method is fuzzy and the accuracy is not high
