Its core function is to assist in observing the distribution of bullet impact points by magnifying the target surface image, providing shooters with a basis for ballistic correction.

However, the external module increases the size of the device, making it inconvenient to carry and set up, and its practicality is limited, especially in complex terrain in the field.
[0004] Therefore, a new technical solution is urgently needed to solve the above-mentioned technical problems. Utility Model Content

[0026] The present invention will be further described in detail below with reference to the accompanying drawings.
[0027] Identical parts are indicated by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "up," and "down" used in the following description refer to directions in the accompanying drawings, while the terms "bottom surface," "top surface," "inner," and "outer" refer to directions toward or away from the geometric center of a specific part, respectively. Specific Implementation Example 1:
[0029] like Figure 1 As shown, a target observation scope with a range-measuring function includes a target observation component and a range-measuring component;
[0030] The target observation assembly includes objective lens group 1, first reflecting mirror 2, second reflecting mirror 3, zoom lens group 4, and eyepiece group 5;
[0031] The ranging component includes a laser emitting module 6, a laser emitting mirror group 7, a laser receiving mirror group 8, and a laser receiving module 9;
[0032] A transmissive display screen 10 electrically connected to the laser receiving module 9 is provided between the zoom lens group 4 and the eyepiece group 5, and a reticle 11 is provided between the second reflector 3 and the zoom lens group 4.
[0033] After the laser emitting module 6 emits a laser beam, the beam passes through the laser emitting mirror group 7, is reflected into the laser receiving mirror group 8, and is finally received by the laser receiving module 9. Upon receiving the laser signal, the laser receiving module 9 calculates the distance signal and displays it on the transmissive display screen 10. By integrating the target observation component and the ranging component, the device size is reduced, and its practicality is improved.
[0034] The laser emitting module 6 and the laser emitting lens group 7 are located below the objective lens group 1. The first reflecting mirror 2 is located on one side of the objective lens group 1 and tilted 20-50° to the optical axis. The second reflecting mirror 3, the laser receiving lens group 8 and the laser receiving module 9 are located on the reflected light path of the first reflecting mirror 2. The second reflecting mirror 3 is tilted 10-40° to the optical axis. The zoom lens group 4 and the eyepiece group 5 are located on the reflected light path of the second reflecting mirror 3.
[0035] The first reflecting mirror 2 is a total reflection mirror, capable of reflecting both visible light and laser light. After entering through the objective lens group 1, visible light is reflected by the first reflecting mirror 2 to the second reflecting mirror 3, and then reflected by the second reflecting mirror 3 to the zoom lens group 4 and the eyepiece group 5, allowing the user to observe a magnified image.
[0036] The surface of the second reflecting mirror 3 is coated with a laser antireflection film, allowing 905nm wavelength lasers to pass through while reflecting visible light in the 400-700nm wavelength range. After being reflected by the objective lens group 1, the laser enters the second reflecting mirror 3 under the action of the first reflecting mirror 2, and directly penetrates the second reflecting mirror 3 under the action of the laser antireflection film, entering the laser receiving mirror group 8 and the laser receiving module 9, thereby calculating the distance information. Specific Implementation Example 2:
[0038] like Figure 2 As shown, unlike specific embodiment 1, the positions of laser emitting module 6 and laser receiving module 9 are swapped (laser emitting mirror group 7 and laser receiving mirror group 8 are the same type of mirror group, so there is no need to swap their positions). After the laser is emitted and passes through the second reflecting mirror 3, the first reflecting mirror 2 can reflect the laser. After the laser is emitted from the objective lens group 1, the reflected laser can enter the laser receiving module 9. Specific Implementation Example 3:
[0040] like Figure 3 As shown, unlike specific embodiment 1, the laser receiving module 9 and the laser receiving mirror group 8 are disposed on one side of the first reflecting mirror 2. The surface of the first reflecting mirror 2 is coated with a laser anti-reflection film, allowing 905nm wavelength laser to pass through and reflecting visible light in the 400-700nm wavelength range. The second reflecting mirror 3 can reflect visible light in the 400-700nm wavelength range. The laser emitted by the laser emitting module 6, after being reflected back, can pass through the eyepiece group and the first reflecting mirror 2 and enter the laser receiving module 9. Specific Implementation Example 4:
[0042] like Figure 4As shown, unlike specific embodiment 3, the positions of the laser emitting module 6 and the laser receiving lens group 8 are swapped. The surface of the first reflecting mirror 2 is coated with a laser anti-reflection film, which allows 905nm wavelength laser to pass through and reflect visible light in the 400-700nm wavelength band. The second reflecting mirror 3 is a total reflection mirror. The laser passes through the beam splitting film 12 on the second reflecting mirror 2 and is emitted from the objective lens group. The reflected laser enters the laser receiving module 9. Specific Implementation Example 5:
[0044] like Figure 5 and Figure 6 As shown, unlike specific embodiment 1, the laser emitting module 6 and the laser emitting lens group 7 are disposed on one side of the first reflecting mirror 2. The central area of the surface of the first reflecting mirror 2 is coated with a beam-splitting film 12, which allows 905nm laser light to pass through, while the remaining area reflects visible light in the 400-700nm band and laser light in the 905nm band. The laser emitted by the laser emitting module 6 passes through the beam-splitting film 12 and is emitted from the objective lens group 1 to the target. The second reflecting mirror 3, the laser receiving lens group 8, and the laser receiving module 9 are disposed on the reflected light path of the first reflecting mirror 2, and the zoom lens group 4 and the eyepiece group 5 are located on the reflected light path of the second reflecting mirror 3.
[0045] The laser emitted from the laser emitting module 6 passes through the laser emitting mirror group 7, penetrates the beam splitter 12 region of the first reflecting mirror 2, and finally exits from the objective lens group 1. The reflected laser enters the target viewing lens from the objective lens group 1, is reflected by the outer region of the beam splitter 12 of the first reflecting mirror 2, passes through the second reflecting mirror 3, and enters the laser receiving mirror group 8 and the laser receiving module 9.
[0046] The beam splitter 12 is arranged in a circular shape and located in the center of the first reflector 2. This avoids the full surface coating from blocking the observation optical path, allowing the beam splitter 12 to reflect visible light and echo laser light while allowing laser light to pass through.
[0047] The surface of the second reflector 3 is coated with a laser anti-reflection film, which allows 905nm wavelength laser to pass through and reflects visible light in the 400-700nm wavelength range, ensuring that the echo laser passes through while reflecting visible light to the eyepiece group 5.
[0048] The specific embodiments are merely explanations of this utility model and are not intended to limit it. After reading this specification, those skilled in the art can make modifications to these embodiments without contributing any inventive step, but such modifications are protected by patent law as long as they fall within the scope of the claims of this utility model.
