[0036] The present application proposes an attachment device and a sighting scope, aiming to solve the problem of user inconvenience in the prior art.

[0037] According to the background information, there are two main types of attachments used on the rear of military and civilian scopes: a side-mounted daylight sight and a night vision sight. In practice, users often need to replace the attachments based on the actual light intensity. However, due to the fixed structures of these two attachments, replacing the attachments on the rear of the scope is complex and difficult, making it inconvenient for users and significantly impacting their experience.

[0038] The embodiment of the present application provides an additional device 200, as shown in Figures 1 to 3, the additional device 200 is applied to a sight, and the additional device 200 includes a housing 210, a CMOS imaging module 220, an eyepiece 300 and a spectroscope 400; the housing 210 is provided with a spectroscopic channel 211, and the spectroscopic channel 211 has an observation port 212; the CMOS imaging module 220 is arranged on one side of the housing 210, and the CMOS imaging module 220 is used for shooting and recording in the visible light band, and for imaging display and shooting and recording in the infrared light band; the eyepiece 300 is detachably arranged on the observation port 212. At the observation port 212, the eyepiece 300 includes an image transmission module 310 and a display screen 320 signal-connected to the image transmission module 310, and the image transmission module 310 is signal-connected to the CMOS imaging module 220; the spectrometer 400 is accommodated in the spectroscopic channel 211, and the spectrometer 400 is tilted relative to the central axis of the observation port 212; the spectrometer 400 is used to transmit part of the visible light band of the light incident on the sight to the observation port 212, and to reflect another part of the visible light band and infrared light band of the light incident on the sight to the CMOS imaging module 220.

[0039] Specifically, the eyepiece 300 is detachably arranged at the observation port 212. When the user uses the sight in a well-lit environment, the eyepiece 300 at the observation port 212 can be removed, and most of the visible light bands of the light entering the sight are transmitted to the observation port 212 through the beam splitter 400, so that the user can observe the field of view of the sight through the observation port 212. At the same time, a small part of the visible light band of the light entering the sight is reflected by the beam splitter 400 to the CMOS imaging module 220, and the CMOS imaging module 220 receives the small part of the visible light band and takes pictures and records, thereby realizing the side shooting function and meeting the user's usage needs in a well-lit environment. When used in an environment with insufficient lighting, the eyepiece 300 can be installed at the observation port 212 so that the image transmission module 310 of the eyepiece 300 is connected to the CMOS imaging module 220 signal, and most of the infrared light bands of the light entering the sight are reflected to the CMOS imaging module 220. The CMOS imaging module 220 receives most of the infrared light bands reflected by the spectrometer 400, and converts them into video signals and transmits them to the image transmission module 310, and finally transmits them to the display screen 320. The display screen 320 displays the infrared night vision image, so that the user can observe the field of view of the sight through the display screen 320, meeting the user's needs for use in an environment with insufficient lighting. The additional device 200 opens a spectroscopic channel 211 with an observation port 212 in the housing 210, installs a CMOS imaging module 220 on one side of the housing 210, and detachably installs the eyepiece 300 at the observation port 212, so that the user can install the eyepiece 300 to the observation port 212 or remove the eyepiece 300 from the observation port 212 according to the actual light intensity, thereby meeting the user's usage needs in environments with different light intensities, and can also realize the side shooting function of the sight. The operation process is simple and convenient, easy for users to use, and can enhance the user experience.

[0040] In this embodiment, the splitting ratio of the visible light band and the infrared light band of the light entering the sight is significantly different, wherein the reflection ratio of the visible light band is less than 50%, and the transmission ratio of the visible light band is greater than 50%; the reflection ratio of the infrared light band is greater than 80%; wherein the visible light band should include 420nm-680nm, and the infrared light band should include 850nm-940nm.

[0041] It should be noted that the principle of infrared imaging is to use infrared detectors, optical imaging objectives and optical scanning systems to receive the infrared radiation energy distribution pattern of the target to be measured (that is, the infrared light band of the light), and reflect it on the photosensitive element of the infrared detector. The optical scanning mechanism then scans the infrared thermal image of the object to be measured and focuses it on a unit or spectroscopic detector. The detector converts the infrared radiation energy into an electrical signal, which is then amplified, converted or displayed as a standard video signal on a TV screen or monitor.

[0042] In one embodiment, as shown in Figure 3, the spectroscopic channel 211 includes a main channel 2111, a transmitted light channel 2112 and a reflected light channel 2113. The main channel 2111 is connected to the transmitted light channel 2112, and the main channel 2111 and the transmitted light channel 2112 are coaxially arranged. The reflected light channel 2113 is located on one side of the intersection of the main channel 2111 and the transmitted light channel 2112. The spectrometer 400 is arranged at the intersection of the transmitted light channel 2112 and the reflected light channel 2113, and the CMOS imaging module 220 is arranged at the end of the reflected light channel 2113 away from the main channel 2111. The spectrometer 400 is tilted from the end away from the CMOS imaging module 220 to the end close to the CMOS imaging module 220 along the direction from the main channel 2111 to the transmitted light channel 2112. Specifically, the transmitted light channel 2112 and the main channel 2111 are located on the same straight line, and the reflected light channel 2113 is arranged crosswise with the main channel 2111. By tilting the spectrometer 400 from the end away from the CMOS imaging module 220 to the end close to the CMOS imaging module 220 along the direction from the main channel 2111 to the transmitted light channel 2112, it can ensure that the spectrometer 400 reflects most of the infrared light bands of the light incident on the light input channel 110 to the CMOS imaging module 220.

[0043] In a specific embodiment, the angle between the beam splitter 400 and the central axis of the main channel 2111 is 45°. Specifically, the central axis of the reflected light channel 2113 is perpendicular to the central axis of the main channel 2111. By tilting the beam splitter 400 at 45° relative to the central axis of the main channel 2111, most of the infrared light bands reflected by the beam splitter 400 are directed along the central axis of the reflected light channel 2113. This allows more infrared light bands to enter the camera of the CMOS imaging module 220, ensuring clear imaging of the CMOS imaging module 220.

[0044] In another specific embodiment, as shown in FIG3 , a reflector 2114 is provided at one end of the reflected light channel 2113 away from the beam splitter 400. The reflector 2114 is configured to reflect the other portion of the visible light band and the infrared light band toward the CMOS imaging module 220. Specifically, the reflector 2114 is provided at the end of the reflected light channel 2113 away from the beam splitter 400. By adjusting the reflector, the other portion of the visible light band and the infrared light band can be directed toward the camera of the CMOS imaging module 220.

[0045] In one embodiment, as shown in Figure 3, the eyepiece 300 also includes a shell 330 and a lens group 340. The shell 330 is threadedly connected to the observation port 212. The image transmission module 310, the display screen 320 and the lens group 340 are arranged in the shell 330 in sequence along the axial direction of the shell 330. The image transmission module 310 is arranged at one end of the shell 330 close to the outer shell 210, and the lens group 340 is arranged at the end of the shell 330 away from the outer shell 210. Specifically, when aiming and shooting, the image transmission module 310 can receive the video signal output by the CMOS imaging module 220 and transmit it to the display screen 320 for display, and the user can view the display screen 320 through the lens group 340, and then observe the field of view of the sight; the eyepiece 300 is threadedly connected to the observation port 212 of the outer shell 210 through the shell 330, so that the eyepiece 300 can be removed from the outer shell 210, so that the user can remove and replace the eyepiece 300; and the eyepiece 300 is installed at the observation port 212 of the outer shell 210 through threads, which can reduce the difficulty of disassembling and installing the eyepiece 300.

[0046] In one embodiment, as shown in FIG4 , a tube clamp 230 is provided on the housing 210. The tube clamp 230 includes a connecting portion 231 and a clamping portion 232. The connecting portion 231 is engaged with the housing 210, and the clamping portion 232 is connected to an end of the connecting portion 231 away from the housing 210. The clamping portion 232 is sleeved on the lens barrel 100 of the sight and is used to clamp the lens barrel 100 of the sight. Specifically, the attachment 200 is mounted on the lens barrel 100 via the clamping portion 232 of the tube clamp 230, which can more firmly mount the attachment 200 on the lens barrel 100 to prevent the attachment 200 from falling off the lens barrel 100. Furthermore, the housing 210 is engaged with the connecting portion 231 of the tube clamp 230. The connection is achieved by a clamping connection, which can reduce the difficulty of mounting the attachment 200 on the sight.

[0047] In a specific embodiment, as shown in Figure 4, the clamping portion 232 has an opening 2321, and locking blocks 2322 are provided on both sides of the opening 2321. The pipe clamp 230 also includes a locking member 240, which can movably pass through any one locking block 2322 and be movably connected to the other locking block 2322. Specifically, the locking member 240 can drive the two locking blocks 2322 to move toward each other, so that the clamping portion 232 clamps the lens barrel 100 to prevent the additional device 200 from falling off the lens barrel 100; further, the locking member 240 includes a locking handle 241 and a locking rod 242, one end of the locking rod 242 passes through the two locking blocks 2322 in sequence and is threadedly connected to the locking handle 241. When the clamping portion 232 clamps the lens barrel 100, that is, when fixing the additional device 200, the user only needs to use a corresponding tool to press the locking rod 242 to prevent the locking rod 242 from rotating, and then rotate the locking handle 241 to make the clamping portion 232 clamp the lens barrel 100. The operation process is simple and convenient.

[0049] Since the sight includes the attachment device 200 as described above, the sight has all the beneficial effects of the attachment device 200, which will not be described in detail here.

[0050] In one embodiment, as shown in FIG5 , the fill light module 500 includes a mounting base 510 and a fill light 520. The mounting base 510 is mounted on the lens barrel 100, and the fill light 520 is disposed on the mounting base 510. Specifically, the fill light 520 has an illumination surface 521.
