Description

Technical Field

[0001] The invention relates to the technical field of telescopes, and in particular to a double-light-path telescope system capable of photographing and visually forming an erect image. Background Art

[0002] The traditional astronomical telescope system is designed as a single optical path system. When taking photos, the camera needs to be installed on the imaging focal plane of the telescope, so visual observation is not possible. If you want to observe visually when taking photos, you need to remove the camera and install the eyepiece for visual observation. At this time, if you need to take photos, you need to focus again after installing the camera to ensure that the camera installation does not affect the image quality. Therefore, it is cumbersome and inconvenient to use, especially for beginners.

[0003] Although current astronomical telescopes can be equipped with a finderscope for visual observation, the finderscope has a small aperture, short focal length, and low magnification, and therefore cannot be compared with a telescope with a long focal length. It can only help users to roughly find the target but cannot see the details of the target clearly.

[0004] Although current binoculars also have dual optical path systems, most of them have relatively short focal lengths and low magnifications, making them unsuitable for photography. Telephoto binoculars are more than twice the size of monoculars with the same focal length, making them large and inconvenient to carry.

[0005] In summary, it is necessary to provide a dual-optical path telescope system that can form an erect image by both photography and visual observation.

[0006] It should be noted that the above contents belong to the technical knowledge of the inventor and do not necessarily constitute prior art. Summary of the invention

[0007] In order to solve the above problems, the object of the present invention is to provide a dual-optical telescope system capable of photographing and visually forming an erect image. To achieve the above-mentioned purpose, the present invention proposes a dual-optical path telescope system capable of photographing and visually forming an erect image, comprising a lens barrel 1, an eyepiece is arranged on one side of the top of the lens barrel 1, the lens barrel 1 and the eyepiece are interconnected, a camera recording mechanism is obliquely arranged at the bottom of the lens barrel 1, a photographing optical path system and a visually forming an erect image optical path structure are arranged inside the lens barrel 1, the visually forming an erect image optical path structure comprises an objective lens, a reflector 1, a reflector 2 and a roof prism arranged inside the lens barrel 1, a fixing seat is arranged in the middle position inside the lens barrel 1, the reflector 1 is fixedly mounted on the fixing seat, the fixing seat can rotate around a rotating shaft, and the objective lens, the reflector 1 and the roof prism form a visual optical path; A reflector 3 is fixedly provided on one side of the interior of the lens barrel 1, and the anti-objective lens, the reflector 3 and the camera imaging mechanism together constitute an imaging optical path system; An optical path switching mechanism is also provided inside the lens barrel 1, and the optical path switching mechanism realizes the switching between the imaging optical path and the visual optical path by driving the reflector 1.

[0008] In one example, the optical path switching mechanism includes a rotating shaft arranged inside the lens barrel, the fixed seat is rotatably connected to the inner wall of the lens barrel through the rotating shaft, a positioning column is fixedly provided on one side of the fixed seat, a fork fixing seat is fixedly provided in the middle of the front side of the lens barrel, a fork is rotatably connected to one side of the fork fixing seat, and a movable sliding groove is provided on the fork.

[0009] In one example, one end of the positioning column passes through an arc-shaped groove formed on the lens barrel and is inserted and connected to the inside of the movable sliding groove.

[0010] In one example, an adjusting hand wheel is provided on the other side of the shift fork fixing seat, and one end of the adjusting hand wheel is fixedly connected to the shift fork.

[0011] In one example, the eyepiece includes an eyepiece barrel, an eyepiece piece is fixedly provided at the upper end of the interior of the eyepiece barrel, an eyepiece focusing seat is fixedly provided in the middle of the interior of the eyepiece barrel, and the roof prism is directly opposite to the eyepiece piece.

[0012] The dual-light-path telescope system capable of photographing and visually forming an upright image proposed by the present invention can bring the following beneficial effects: 1. The present invention provides a dual optical path system of a camera optical path system and a visual erecting optical path structure, which can visually observe the erecting image and take pictures, and both systems are realized by the same objective lens and can maintain the same focal length; 2. The photographic optical path system of the present invention uses only one reflector to change the direction of the optical path, thereby reducing the size of the telephoto telescope. A single reflection reduces the loss of light energy and aberration, thereby improving the brightness and quality of the image.

[0013] 3. The visual optical path system of the present invention is composed of two plane reflectors and a roof prism. The optical path is switched by setting an optical path switching mechanism to rotate and change the angle position of one reflector. The reflected light passes through the second plane reflector and then reflects onto the roof prism. Then, it is reflected to the eyepiece end through the roof prism to realize the observation target to form a positive image. In summary, the telescope dual-optical path system of the present invention can not only meet the dual needs of visualizing and photographing the target observed using the same telescope at the same time, but also has a small size and is easy to carry.

The optical path switching mechanism realizes the switching of the camera optical path and the visual optical path by driving the reflector 2. The optical path switching mechanism includes a rotating shaft 8 arranged inside the lens barrel 14. The fixed seat 9 is rotatably connected to the inner wall of the lens barrel 14 through the rotating shaft 8. A positioning column 10 is fixedly provided on one side of the fixed seat 9. A shift fork fixing seat 12 is fixedly provided in the middle of the front side of the lens barrel 14. A shift fork 11 is rotatably connected to one side of the shift fork fixing seat 12. A movable slide groove 11-1 is provided on the shift fork 11. One end of the positioning column 10 passes through the arc groove provided on the lens barrel 14 and is inserted and connected to the inside of the movable slide groove 11-1. An adjusting hand wheel 13 is provided on the other side of the shift fork fixing seat 12. One end of the adjusting hand wheel 13 is fixedly connected to the shift fork 11.

After being reflected by the roof prism 5, the light enters the eyepiece 6. The target seen in the eyepiece 6 is consistent with the target seen by the naked eye in the direction (up, down, left, and right), so that the target positive image is observed. When it is necessary to switch the light path, the adjusting hand wheel 18 can be rotated, and the adjusting hand wheel 18 drives the fork 11 to rotate, thereby acting on the positioning column 10. The positioning column 10 moves in the arc groove and acts on the fixing seat 9 at the same time. The fixing seat 9 rotates under the action of the rotating shaft 8, thereby driving the reflector 1 2 to rotate. When it is rotated to Figure 4 When the telescope is in the middle position, it switches to the camera optical path, thereby realizing the dual needs of visualizing and photographing the target observed with the same telescope.
