technical field

The utility model relates to astrophotography equipment, in particular to an atmospheric chromatic aberration correction mirror.

Background technique

Astronomy is the science based on observation. In the early days of astronomy, astronomers studied brightly glowing stars visible to the human eye. With the gradual deepening of science, astronomers began to study those celestial bodies that are farther away from the earth and darker and invisible to the naked eye, so they began to use telescopes. At first, combined monocular telescopes (refractor telescopes for short) It is a Newtonian reflecting telescope.

With the gradual development of astronomical science theory, it has also greatly promoted the rapid development of astronomical instruments, especially photoelectric devices that respond to optical signals and are sensitive. Due to the refraction of the atmosphere on the optical signal, the optoelectronic device will have different effects on the optical model, resulting in the error of the optical signal received by the optoelectronic device. The Atmospheric Chromatic Aberration Correction Mirror has well corrected the influence of the atmosphere on the refraction of light.

detailed description

Below, the substantive features and advantages of the utility model are further described in conjunction with examples, but the utility model is not limited to the listed embodiments.

As shown in Figures 1 to 4, the atmospheric chromatic aberration correcting mirror 100 of the present embodiment comprises a first wedge mirror 1, a second wedge mirror 2, a filter frame, a frame cover 3, a handle and a lens barrel 4, the first One, the second optical wedge mirror 1,2 is arranged on the filter frame, the first and second optical wedge mirrors are arranged at intervals and can be rotated, the filter frame is arranged in the frame cover 4, and the filter frame can be placed in the frame cover The frame cover 3 is provided with a rotation groove, the handle is arranged on the filter frame, and protrudes through the rotation groove, and the handle can move in the rotation groove. In the above technical solution, the filter frame is rotated by operating the handle, so that the first and second wedge mirrors can be rotated. Through the rotation of the two optical wedge mirrors, the refraction of the atmosphere is offset.

As shown in Figures 1 to 4, further, the frame cover includes a first filter frame 5 and a second filter frame 6, and the handle includes a first handle 7 and a second handle 8, the first handle 7 is arranged on the On the first filter frame 5, the second handle 8 is arranged on the second filter frame 6, and the first and second optical wedge mirrors can be adjusted respectively through the first and second handles. Described rotating groove comprises first rotating groove 31 and second rotating groove 32, and first rotating groove 31 is positioned at the top of second rotating groove 32, and first handle 7 protrudes through first rotating groove 31, and second handle 8 passes through second rotating groove. The slot 32 protrudes. When the first and second handles are overlapped, the thickest sides of the first and second wedge mirrors overlap (as shown in FIG. 4 ). While rotating the handle, the filter frame is driven to rotate, so that the two largest sides of the first and second wedge mirrors do not overlap. When the largest sides of the two optical wedge mirrors do not overlap, when the light passes through the first and second optical wedge mirrors, refraction is formed because the refractive index of glass is different from that of air. In this embodiment, the first and second optical wedge mirrors 1 and 2 are made of glass, and one side of the optical wedge mirror is horizontal and the other side is inclined. The atmospheric chromatic aberration correcting mirror 100 also includes an adapter ring 9, and the adapter ring 9 presses the filter frame so that it cannot fall out. In this embodiment, the adapter ring 9 is a 1.25 inch adapter ring, and the lens barrel 4 is M42 to 1.25 inch. The first and second wedge mirrors 1 and 2 are glued to the filter frame by insulating glue, and the filter frame is installed in the frame cover. From M42 to 1.25 inches and the 1.25 inches adapter ring presses the filter frame so that it cannot fall out. The fit between the filter frame and the frame cover is clearance fit, so that the filter frame can rotate freely in the frame cover. The atmospheric chromatic aberration correcting mirror also includes a dial 10, and the dial 10 is sleeved on the outside of the mirror frame cover.
