Description

A dual-beam telescope system capable of both photographic and visually upright images. Technical Field

[0001] This invention relates to the field of telescope technology, and in particular to a dual-beam telescope system capable of both photographing and visually forming an upright image. Background Technology

[0002] Traditional astronomical telescope systems are single-optical-path designs. When taking photographs, the camera must be mounted on the telescope's focal plane, making visual observation impossible. If visual observation is desired during photography, the camera must be detached, an eyepiece installed, and then refocused after reassembly to ensure the camera's placement doesn't affect image quality. This process is cumbersome and inconvenient, especially for beginners.

[0003] Although astronomical telescopes can currently be equipped with a finder scope for visual observation, finder scopes have small apertures, short focal lengths, and low magnification. Therefore, they cannot be compared with telescopes with long focal lengths. They can only help users to roughly locate targets but cannot see the details of the targets clearly.

[0004] While current binoculars are also dual-optical-path systems, most have relatively short focal lengths and low magnification, making them unsuitable for photography. Long-focal-length binoculars are more than twice the size of monoculars of the same focal length, making them bulky and inconvenient to carry.

[0005] In summary, there is a need for a dual-beam telescope system that can be used for both photography and visual image formation.

[0006] It should be noted that the above content falls within the inventor's technical knowledge and does not necessarily constitute prior art. Summary of the Invention

[0007] To address the aforementioned problems, the objective of this invention is to provide a dual-beam telescope system capable of both photographic and visually upright image formation.

[0008] To achieve the above objectives, this invention proposes a dual-beam telescope system capable of both photography and visually erecting images. The system includes a telescope tube, an eyepiece located on one side of the top of the tube, and interconnectedness between the tube and the eyepiece. A camera mechanism is obliquely mounted at the bottom of the tube. The tube contains both a camera optical path system and a visually erecting optical path structure. The visually erecting optical path structure includes an objective lens, a first reflecting mirror, a second reflecting mirror, and a roof prism disposed within the tube. A mounting base is located in the middle of the tube, and the first reflecting mirror is fixedly mounted on the base. The base is rotatable around a pivot. The objective lens, the first reflecting mirror, and the roof prism form the visual optical path.

[0009] A third reflector is fixedly installed on one side inside the first lens barrel. The mirror, the third reflector, and the camera mechanism together form the imaging optical path system.

[0010] The lens barrel is also equipped with a light path switching mechanism, which switches between the camera light path and the visual light path by driving the reflector.

[0011] In one example, the optical path switching mechanism includes a rotating shaft disposed inside the lens barrel, the fixed seat being rotatably connected to the inner wall of the lens barrel via the rotating shaft, a positioning post being fixedly provided on one side of the fixed seat, a fork fixing seat being fixedly provided in the middle of the front of the lens barrel, a fork being rotatably connected to one side of the fork fixing seat, and a movable sliding groove being provided on the fork.

[0012] In one example, one end of the positioning post passes through an arc-shaped groove on the lens barrel and is interlocked inside the movable slide.

[0013] In one example, an adjusting handwheel is provided on the other side of the shift fork fixing seat, and one end of the adjusting handwheel is fixedly connected to the shift fork.

[0014] In one example, the eyepiece includes an eyepiece tube, an eyepiece lens is fixedly disposed at the upper end of the eyepiece tube, an eyepiece focusing mount is fixedly disposed in the middle of the eyepiece tube, and the roof prism is positioned opposite the eyepiece lens.

[0015] The dual-beam telescope system proposed in this invention, capable of both photographic and visually upright images, offers the following advantages:

[0016] 1. This invention, by setting up a dual-light-path system of a camera light path system and a visually upright image light path structure, can both visually observe upright images and take pictures, and both systems are implemented through the same objective lens, which can maintain the same focal length;

[0017] 2. The photographic optical path system of the present invention uses only one reflector to change the direction of the optical path, reducing the size of the telephoto telescope. Single reflection reduces light energy loss and aberration, and improves the brightness and quality of the image.

[0018] 3. The visual optical path system of the present invention consists of two plane mirrors and a roof prism. By setting a light path switching mechanism to rotate and change the angle position of one of the mirrors, the light path is switched. The reflected light is reflected by the second plane mirror and then reflected by the roof prism to the eyepiece end, so as to realize that the observed target is formed into an upright image.

[0019] In summary, the dual-optical-path telescope system of the present invention not only meets the dual requirements of visual observation and photography of the target observed using the same telescope, but is also compact and portable. Attached Figure Description

[0032] As shown in Figures 1 to 3, an embodiment of the present invention proposes a dual-beam telescope system capable of both photography and visually upright imaging. The system includes a telescope tube 14, an eyepiece 6 on one side of the top of the tube 14, and interconnections between the tube 14 and the eyepiece 6. A camera mechanism 18 is obliquely arranged at the bottom of the tube 14. The tube 14 contains a camera optical path system and a visually upright imaging optical path structure. The visually upright imaging optical path structure includes an objective lens 1, a reflector 2, a second reflector 3, and a roof prism 5 disposed inside the tube 14. A mounting base 9 is located in the middle of the tube 14, and the reflector 2 is fixedly mounted on the mounting base 9. The objective lens 1, the reflector 2, and the roof prism 5 form the visually upright optical path.

[0033] An objective lens 1, a reflector 4, and a camera mechanism 18 are fixedly installed on one side inside the lens barrel 14 to form an imaging optical path system.

[0034] The lens barrel 14 is also equipped with a light path switching mechanism. The light path switching mechanism realizes the switching between the camera light path and the visual light path by driving the reflector 2. The light path switching mechanism includes a rotating shaft 8 set 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 post 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 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 opened on the shift fork 11. One end of the positioning post 10 passes through the arc-shaped groove opened on the lens barrel 14 and is inserted into the interior of the movable slide groove 11-1. An adjusting handwheel 13 is provided on the other side of the shift fork fixing seat 12. One end of the adjusting handwheel 13 is fixedly connected to the shift fork 11.

[0035] The eyepiece 6 includes an eyepiece tube 16, an eyepiece sheet 17 is fixedly provided at the upper end of the eyepiece tube 16, and an eyepiece focusing seat 7 is fixedly provided in the middle of the eyepiece tube 16. The roof prism 5 is positioned opposite the eyepiece sheet 17.

[0036] Working principle: As shown in Figures 3 and 5, light rays from a distance (up, down, left, and right) converge on the reflective surface of mirror 2 after passing through objective lens 1, and are reflected again onto the reflective surface of mirror 3, and then onto the roof prism 5. After being reflected by the roof prism 5, the light rays enter the eyepiece 6. The target seen in the eyepiece 6 is in the same direction (up, down, left, and right) as the target seen with the naked eye, thus observing a positive image of the target. When it is necessary to switch the optical path, the adjustment handwheel 18 can be rotated. The adjustment handwheel 18 drives the shift fork 11 to rotate, which in turn acts on the positioning post 10. The positioning post 10 moves in the arc groove and simultaneously acts on the fixing seat 9. The fixing seat 9 rotates under the action of the rotating shaft 8, which in turn drives mirror 2 to rotate. When it rotates to the position shown in Figure 4, the imaging optical path is switched, thus realizing the dual needs of visual observation and imaging of the target observed using the same telescope.

[0037] The various embodiments in this specification are described in a progressive manner. Similar or identical parts between embodiments can be referred to mutually. Each embodiment focuses on describing the differences from other embodiments. In particular, the system embodiments are basically similar to the method embodiments, so the description is relatively simple; relevant parts can be referred to the descriptions in the method embodiments.

[0038] The above description is merely an embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principle of the present invention should be included within the scope of the claims of the present invention.
