Description

TECHNICAL FIELD

[0001] The utility model belongs to telescopic technical field, concretely relates to a kind of high-definition synchronous photographing telescope. BACKGROUND

[0002] Monocular telescope is the single eye observation telescopic imaging system consisting of a group of eyepiece, prism and objective lens. Binoculars, also known as "binocular telescope". It is composed of two monocular telescopes in parallel. The distance between the two eyepieces can be adjusted to allow both eyes to observe at the same time, thereby obtaining a stereoscopic effect. Its structure is to install a pair of reflecting prisms between the objective lens and the eyepiece, so that the incident light is reflected multiple times in the barrel to shorten the length of the barrel, and at the same time, the inverted image formed by the objective lens is inverted again to become a positive image. This device is simply called "prism telescope", which has a larger field of view and is commonly used for navigation, military surveillance and field observation. In actual use, it is necessary to take pictures of the observed target for preservation, but the conventional telescope does not have this function.

[0003] The prism telescope commonly used is Schmidt-Berger prism, which can rotate the image by 180° and is usually used as an "image erecting system" in binoculars. This prism group is composed of two half-pentagonal prisms separated by an air gap and a ridge prism. Multiple total reflections cause the image to be flipped in the vertical direction, and the image is flipped laterally at the "roof" of the ridge prism, resulting in a 180° rotation of the image. The image does not change its rotational direction. The existing half-pentagonal prism used in telescopes has three main working planes. The first plane is a light transmission plane, the second plane is a total reflection plane without coating, and the third plane is a reflective plane coated with a reflective film. Light enters the first plane, is totally reflected by the second plane, and is reflected on the reflective film-coated third plane. After reflection, a cylindrical beam of light exits the second plane of the half-pentagonal prism and enters the ridge prism for reflection. Finally, it passes through the eyepiece system and enters the visual system, where people can see the object.

[0004] There are also related patents about photographing telescopes in the prior art, such as: CN1409170A, published on April 9, 2003, an optical viewer device with photographic function, which includes: a telescope optical system for observing an object; a digital camera system for taking a picture of the object. 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 to focus the object through the telescope optical system and the camera lens system.

[0005] A kind of long-distance synchronous observation camera disclosed in publication number CN2550814Y disclosed date 2003.05.14 is mainly composed of telescopic system and camera system, wherein the telescopic system includes monocular telescope and binocular telescope, and the monocular telescope is connected in parallel with the binocular telescope through a connecting bridge plate, a digital camera is installed behind the eyepiece of the monocular telescope, and a synchronous linkage device is further installed in parallel in front of the connecting bridge plate, when the target observed at a distance is observed through the telescopic system by adjusting the synchronous linkage device, the digital camera can automatically record the target observed by pressing the shutter.

[0006] Publication number CN2502286Y disclosed date 2002.07.24 is mainly about a telescope with a synchronous image capturing device, especially a telescope with another single tube and an image capturing device. When using the telescope to observe a distant object, the image capturing device can be used to take a picture of the object for future observation or research.

[0007] The above-mentioned telescope is large and heavy, and the photographing and observation are two systems, the fields of view are different, and the photographed picture is not the same as the scene observed from the telescope.

[0008] Publication number CN221926803 disclosed date U2024.10.29 is a portable handheld intelligent photographing telescope, which includes a shell, an optical system, and a video recording and photographing system. The optical system is arranged in the shell, the photographing system is arranged in the shell, and the video recording and photographing system is arranged beside the optical system. The camera of the video recording and photographing system is aligned with the light splitting prism of the optical system. The light used by the photographing system in this patent scheme is taken from the light in the optical system, thereby reducing the light entering the eyepiece, causing the brightness of the scene observed by the eyes through the eyepiece to be low, the scene to be dim, and the color freshness to be poor. The picture and video of the photographing and recording are dark and unclear. SUMMARY

[0009] To solve the above-mentioned defects in the prior art, the purpose of the present application is to provide a high-definition synchronous photographing telescope with a compact structure, which can realize observation by the human eye and operation of photographing at the same time. The photograph taken by photographing is exactly the same as the scene observed from the eyepiece, and the picture is clear, without affecting the clarity of the telescope observation.

[0010] To achieve the above-mentioned purpose, the technical scheme of the present application is as follows:

[0011] The application discloses a high-definition synchronous photographing telescope, which comprises an optical objective system, an optical erecting system and an optical eyepiece system, wherein the optical erecting system adopts a Schmidt-Pechan prism, and the Schmidt-Pechan prism is composed of a half-pentaprism and a roof prism. Roof prism The first reflecting surface of the half-pentaprism is coated with a first reflecting film, and a half-pentaprism light exit hole is arranged on the first reflecting film; the light entering the half-pentaprism is emitted through the half-pentaprism light exit hole and enters the roof prism, and the light is emitted into the optical eyepiece system through

[0012] The second reflecting surface of the half-pentaprism is coated with a second reflecting film, and a photographing light transmission hole is arranged on the second reflecting film; the light entering the roof prism is partially emitted into a photographing and / or video shooting system through the photographing light transmission hole.

[0013] Preferably, the photographing light transmission hole is matched with a prism for changing the light emission direction, and the light emitted from the photographing light transmission hole enters the photographing and / or video shooting system after being turned by the prism.

[0014] Preferably, the position of the half-pentaprism light exit hole is coated with an anti-reflection film.

[0015] Preferably, a photographing light transmission hole is arranged on the wall of the lens barrel, and the light emitted from the photographing light transmission hole for photographing or video shooting enters the photographing and / or video shooting system through the photographing light transmission hole.

[0016] Preferably, a fixing seat is arranged on the wall of the lens barrel at a position corresponding to the photographing light transmission hole, and a lens of the photographing and / or video shooting system is fixed on the fixing seat; and a fine adjustment structure for adjusting the optical axis of the lens is arranged on the fixing seat.

[0017] Preferably, the fine adjustment structure is three fine adjustment screws arranged on the side wall of the fixing seat.

[0018] Preferably, the photographing and / or video shooting system comprises a lens and a CCD sensor, and the lens is a high-definition lens.

[0019] The beneficial effects of the above technical scheme are: the high-definition synchronous photographing telescope is capable of photographing or shooting videos, and the scene viewed from the eyepiece is completely identical in terms of field of view and depth of field. It is a telescope that truly realizes the complete identity of the observation result of the human eye through the telescope and the shooting result, does not affect the normal human eye observation of the eyepiece, and has clear shooting effect. The light used for photographing and shooting of the telescope is guided into the optical photographing system from the light in the barrel of the telescope to realize photographing. Specifically, the light path of the telescope is composed of an optical objective system, a Schmidt-Pechan prism, and an optical eyepiece system. The Schmidt-Pechan prism of the utility model is an improved prism group. The first reflecting surface of the existing half-pentagonal prism reflects light according to the principle of total reflection of light. A first reflecting film is coated on the first reflecting surface of the half-pentagonal prism. A half-pentagonal prism light exit hole is arranged on the first reflecting film. The light entering the half-pentagonal prism is emitted through the half-pentagonal prism light exit hole and enters the roof prism. The light enters the optical eyepiece system through the roof prism. A second reflecting film is coated on the second reflecting surface of the half-pentagonal prism. A photographing light transmission hole is arranged on the second reflecting film. The light entering the roof prism is partially transmitted through the photographing light transmission hole and enters the photographing and / or shooting system. The first reflecting film of the half-pentagonal prism can reflect all the light entering the half-pentagonal prism to the second reflecting surface. The light that does not reach the critical angle of total reflection is also reflected, reducing the loss of light and improving the intensity of the effective light. The light intensity of the light entering the eyepiece is ensured by the light output amount of the half-pentagonal prism light exit hole, so that the human eye observation is clearer and more true. The light of the photographing and / or shooting system is taken at the new half-pentagonal prism, specifically through the photographing light transmission hole arranged on the second reflecting film. The light transmitted through the hole enters the photographing and / or shooting system to realize shooting or photographing. Since the light of the photographing and / or shooting system is taken from the light entering the objective system of the telescope, the image photographed or shot is completely identical to the scene observed by the human eye from the eyepiece, truly realizing synchronous photographing and telescoping. The prior art, such as a portable handheld intelligent photographing telescope with publication number CN221926803 and publication date October 29, 2024, divides light at the front end position of the eyepiece by using a light splitting prism to realize photographing. This light splitting structure divides the light that is not converged, and the image formed in the video recording and photographing system is not clear and has poor color reproduction. More importantly, the light entering the objective lens of the telescope is weakened by the action of multiple reflections, refractions, and diaphragms, and only reaches the required range of clear observation. However, the light splitting structure affects the light transmission amount entering the eyepiece, resulting in low brightness of the scene observed by the eyepiece and unclear scene image.The light is taken at the half-pentagonal prism position, the light intensity of the light entering the objective lens system is high, the first reflecting film is coated on the first reflecting surface of the half-pentagonal prism, and the light loss is further reduced, part of the light in the half-pentagonal prism is emitted through the light emission hole of the half-pentagonal prism and enters the ocular lens system to meet the quality requirement of human eye observation, and the other part of the light in the half-pentagonal prism enters the photographing and / or video shooting system through the photographing light transmission hole formed in the second reflecting film, and the definition of the video shooting and photographing can also be ensured.

[0020] The half-pentagonal prism in the system plays a crucial role in the synchronous photographing function, which not only meets the normal observation effect of the telescope, but also meets the photographing function using the same objective lens system. The high-reflecting film is coated on the maximum plane of the half-pentagonal prism, and the anti-reflection film is coated at the position of the light emission hole of the half-pentagonal prism, the light transmission amount is increased, the photographing system effect is improved by more than 80%, and the original observation effect is also improved by more than 10%. The biggest advantage of the device is that the observation result and the video shooting result at a long distance are completely the same, and the clear picture or video of observation can be saved, so that the single function of the ordinary telescope and the camera is solved.
