Description

Technical Field

[0001] The utility model belongs to the technical field of telescopes, and in particular relates to a telescope with a photographing function. Background Art

[0002] A monocular telescope is a single-eye observation telescopic imaging system composed of a set of eyepieces, prisms and objective lenses. Binoculars, also known as "binoculars", are telescopes composed of two monocular telescopes placed side by side. The distance between the two eyepieces can be adjusted so that both eyes can observe at the same time to obtain a three-dimensional effect. Its structure is to install a pair of total reflection prisms between the objective lens and the eyepiece, so that the incident light undergoes multiple total reflections in the lens barrel to shorten the length of the barrel. At the same time, the inverted image formed by the objective lens can be inverted to become an upright image. This device is referred to as a "prism telescope" and has a large field of view. It is often used in navigation, military reconnaissance, and field observation. In actual use, it is necessary to take pictures of the observed target and save it. Conventional telescopes do not have this function. There are also related patents about photographic telescopes in the prior art, such as:

The digital camera system includes a CCD sensor and an optical camera system, which are connected to each other so that the object forms a photographic image on the light receiving surface of the sensor through the optical camera system. An automatically operated focusing mechanism is connected to the telescope optical system and the camera lens system so that the object is focused through the telescope optical system and through the camera lens system.

[0005] Publication No. CN2502286Y Publication Date 2002.07.24 The utility model is mainly related to a telescope with a synchronous image capture device, and more particularly to a telescope with another single tube and an image capture device added to the telescope. Thus, when viewing a distant object through the telescope, the image capture device can be used to take a photo of the object for later viewing or research.

[0006] The above-mentioned telescopes are large and bulky, and photography and observation are two systems with different fields of view. The photographed pictures are not exactly the same as the scenes observed through the telescope. Summary of the invention

[0007] In order to solve the above-mentioned defects in the prior art, the purpose of the utility model is to provide a telescope with a photographing function, which has a compact structure and can realize the functions of observation and photographing at the same time, and the observation result is exactly the same as the photographing result.

[0008] To achieve the above-mentioned purpose, the utility model adopts a technical solution: the telescope with a photographing function has a telescope optical system, the telescope optical system includes an optical objective lens system, an optical erecting system and an optical eyepiece system for observing an object, and is characterized in that: the optical erecting system adopts a Schmidt-Hahn prism, the Schmidt-Hahn prism is composed of a roof prism and an auxiliary prism, the auxiliary prism is plated with a reflective film, a light transmission hole is opened on the reflective film, the light transmission hole is matched with a prism, a photographic light through hole is opened on the wall of the lens barrel, an optical photographic system is arranged at the position of the photographic light through hole, the prism redirects the light transmitted from the light transmission hole to the photographic light through hole on the wall of the lens barrel, and the light forms a photo image on the CCD sensor after being adjusted by the optical photographic system.

[0009] A fixing seat is arranged on the lens barrel wall at a position corresponding to the photographic light through hole, the optical photographic system is sleeved in the fixing seat, and an optical axis fine-tuning structure for the optical axis position of the optical photographic system is arranged on the fixing seat.

[0010] The optical axis fine-tuning structure is three fine-tuning screws evenly distributed on the side wall of the fixing seat.

[0011] The photographic light through hole is located at the center of the reflective film on the auxiliary prism.

[0012] The area of ​​the photographic light passage hole accounts for 5-10% of the area of ​​the reflective film on the auxiliary prism.

[0013] The beneficial effects of the above technical solution are as follows: the image taken by the telescope with a photographing function is exactly the same as the image during observation, both in terms of field size and depth of field. It is a telescope that truly realizes that the observation result of the human eye through the telescope is exactly the same as the video recording result. The light used for photographing by the telescope is the light entering a lens barrel of the telescope and is guided to the optical photographic system to achieve photographing. Specifically, the optical path of the telescope is composed of an objective lens system, a Schmidt-Bergham prism and an eyepiece system. The Schmidt-Bergham prism is composed of a roof prism and an auxiliary prism. The auxiliary prism is coated with a reflective film. The Schmidt-Bergham prism realizes the up-down and left-right exchange of the incident light, thereby converting the inverted image formed by the objective lens into an upright image, and realizing the observation of distant targets through the eyepiece. The utility model has a light transmission hole on the reflective film of the auxiliary prism in the Schmidt-Bergham prism. When the light entering the lens barrel is irradiated by the light transmission hole, it is no longer reflected. Instead, the light transmitted through the light transmission hole is turned to the direction on the lens barrel wall by the added prism to form a photographic light. A photographic light through hole is opened on the lens barrel wall. The photographic light enters the optical photographic system fixed on the outer wall of the lens barrel through the photographic light through hole, and forms a photo image on the CCD sensor, thereby realizing photo storage. The greatest advantage of the device is that the observation result at a long distance is exactly the same as the photo shooting result, thereby solving the problem that the single function of ordinary telescopes and cameras, that is, ordinary telescopes are only for observation but cannot simultaneously shoot and ordinary cameras can only take photos at close range but cannot simultaneously shoot distant targets.
