[0038] Please refer to the reference. Figures 1 to 5According to a first aspect embodiment of the present invention, the optical device adapted to a multi-wavelength scanning device includes a housing 1, a lens 2, a mounting base 3, and a filter 4. The housing 1 has a mounting cavity and a lens hole 121 communicating with the mounting cavity; the lens 2 is installed in the mounting cavity and is disposed corresponding to the lens hole 121; the mounting base 3 is disposed on the outside of the housing 1 and is disposed corresponding to the lens hole 121, and the mounting base 3 is detachably connected to the housing 1; the filter 4 is installed on the mounting base 3 and covers the lens hole 121.

[0039] According to the optical device for adapting to multi-wavelength scanning equipment according to an embodiment of the present invention, a lens 2 is mounted through the mounting cavity of the housing 1, and the lens 2 can take pictures outward through the lens hole 121. Simultaneously, a mounting base 3 is placed on the outside of the housing 1 for mounting and fixing a filter 4. The filter 4 covers the lens hole 121. When subjected to full-spectrum interference and requiring the use of a specific color light source, a narrow-pass filter 4 of the corresponding color channel or a low-pass filter 4 can be used to filter out stray light that is prone to interference. The mounting base 3 and the filter 4 are detachably fixed to the outside of the lens hole 121, making installation and removal convenient. This allows for easy replacement of different filters 4 according to the usage scenario, and the filter 4 can be easily removed when not needed, flexibly adapting to various indoor and outdoor application scenarios.

[0040] For example, if the device has both blue (460nm) and infrared (850nm) light sources, and internally includes dual narrow-pass filters 4 for these two wavelengths, when the blue light source is needed due to full-spectrum interference, the narrow-pass filter 4 of the blue channel or a low-pass filter 4 can be used to filter out stray light in the 850nm band that is prone to interference. Conversely, when using the infrared light source, the narrow-pass filter 4 of the infrared channel or a high-pass filter 4 can be used to ensure the device is in optimal working condition. The mounting base 3 and the filter 4 can be detachably connected by snap-fit, threaded, or magnetic connections, etc., and are not limited here.

[0041] According to one embodiment of the present invention, the optical device adapted to a multi-wavelength scanning device includes a magnetic component 5, which is installed in the mounting cavity to fix the mounting base 3 and the filter 4 outside the lens hole 121 by magnetic attraction.

[0042] Understandably, the magnetic component 5 can be an ordinary magnet or an electromagnet, and the mounting base 3 can also be made of magnetic material, so that the magnetic component 5 can attract the mounting base 3 and fix the mounting base 3 to the outer wall of the housing 1, thereby preventing the filter 4 from falling off. For example, the mounting base 3 is made of iron, and the magnetic component 5 is attached to the inner wall of the mounting cavity. When the mounting base 3 is attached to the outer wall of the housing 1, the magnetic component 5 can fix the mounting base 3 by magnetic attraction. Of course, in other embodiments, the mounting base 3 can also be made of plastic or other materials, and magnetic material or magnets can be embedded in the mounting base 3. As long as the mounting base 3 can be attracted by the magnetic component 5 to fix the filter 4, it is acceptable. It should be noted that the mounting base 3 can abut against the edge of the outer wall of the housing 1 near the lens hole 121 without obstructing the lens hole 121, so as not to block the lens 2 from shooting. In this way, the user can install or remove the mounting base 3 at any time in specific scenarios to use the filter 4 to cover the lens 2 or not use the filter 4, which is convenient and quick to operate.

[0043] like Figure 2 As shown, in one embodiment, the optical device adapted to the multi-wavelength scanning device includes a fill light 6, which is mounted on the housing 1 and exposed on the outer wall of the housing 1, and is disposed near the lens hole 121.

[0044] According to one embodiment of this utility model, the optical device adapted to a multi-wavelength scanning device includes multiple magnetic elements 5, which are arranged around the lens aperture 121. It is understood that the multiple magnetic elements 5 enhance the attraction force to ensure the installation stability of the filter 4 and the mounting base 3, preventing them from easily falling off. Simultaneously, the multiple magnetic elements 5 surrounding the lens aperture 121 attract the mounting base 3 located on the outer wall of the housing 1, ensuring uniform force around the mounting base 3. Furthermore, the installation position of the magnetic elements 5 is reasonable and will not obstruct the lens 2 from taking pictures.

[0045] like Figure 1 As shown, according to one embodiment of the present invention, the outer shell 1 includes a shell body 11 and a front shell 12. The shell body 11 is provided with a mounting groove. The front shell 12 is connected to the shell body 11 to cover the opening of the mounting groove and form a mounting cavity. The front shell 12 has a lens hole 121. The mounting seat 3 and the filter 4 are installed on the outside of the front shell 12, and the magnetic component 5 is installed on the inside of the front shell 12.

[0046] Optionally, the front shell 12 and the shell body 11 can be connected by screws, snap-fit ​​connections, or adhesive bonding, etc., without limitation. Snap-fit ​​connection is used as an example here to facilitate the assembly and disassembly of the front shell 12 and the shell body 11 without the need for other tools. It should be noted that the inner side of the front shell 12 refers to the side of the front shell 12 located within the mounting cavity, and the outer side of the front shell 12 refers to the side of the front shell 12 facing away from the mounting cavity. During installation, the magnetic component 5 can be first fixed to the inner side of the front shell 12, and then the front shell 12 can be connected to the shell body 11 for easy installation. The installation method of the magnetic component 5 and the front shell 12 can be snap-fit, adhesive bonding, threaded connection, etc., without limitation. The front shell 12 has a lens hole 121, meaning that during installation, the lens hole 121 corresponds to the lens 2 installed in the mounting groove, allowing the lens 2 to take pictures through the lens hole 121.

[0047] According to one embodiment of this utility model, a limiting groove is formed on the inner side of the front shell 12, and the magnetic component 5 is accommodated and confined within the limiting groove. The limiting groove is formed by the inward recess of the inner wall of the front shell 12, reducing the wall thickness of the front shell 12. Installing the magnetic component 5 within the limiting groove brings it closer to the mounting base 3, enhancing their mutual attraction and improving connection stability. Simultaneously, the magnetic component 5 can be interference-fitted with the inner wall of the limiting groove; it can be easily installed by pressing it into the limiting groove.

[0048] According to one embodiment of the present invention, the filter 4 is threadedly connected to the mounting base 3. For example, the filter 4 has an external thread on its edge, and the mounting base 3 has a corresponding receiving groove for accommodating the filter 4. An internal thread is correspondingly provided on the inner wall of the receiving groove. The external thread of the filter 4 engages with the internal thread of the receiving groove to improve the connection stability between the filter 4 and the mounting base 3, preventing the filter 4 from shaking and affecting the shooting effect.

[0049] According to one embodiment of the present invention, the mounting base 3 includes a mounting ring and a ring protrusion. The ring protrusion is located on the side of the mounting ring facing the outer shell 1 and abuts against the outer shell 1 so that the mounting ring, the ring protrusion and the outer wall of the outer shell 1 enclose and form a receiving space, and the filter 4 is received in the receiving space.

[0050] Understandably, the mounting ring surrounds the periphery of the lens aperture 121 to avoid obstructing it. Simultaneously, the annular protrusion abuts against the outer wall of the housing 1, creating a space between the mounting ring and the outer wall to accommodate the filter 4. During installation, the filter 4 can be first mounted on the annular protrusion, and then the annular protrusion abuts against the outer wall of the housing 1. The magnetic component 5 then attracts either the annular protrusion or the mounting ring, fixing the mounting base 3 and the filter 4 to the outer wall of the housing 1 corresponding to the lens aperture 121.

[0051] According to one embodiment of this utility model, the filter 4 is installed with an interference fit to the annular protrusion. It is understood that pressing the filter 4 into the ring formed by the annular protrusion is convenient. To facilitate the removal and replacement of the filter 4, a notch can be made on the annular protrusion, allowing a tool to be inserted through the notch to pry out the filter 4. Of course, in other embodiments, when replacing different filters 4, the mounting base 3 can be replaced together, thus eliminating the need to disassemble the filter 4 and the mounting base 3.

[0052] According to one embodiment of this utility model, the annular protrusion is provided with a buckle, and the filter 4 is fastened to the buckle. For example, buckles are provided on opposite side walls of the annular protrusion, and the filter 4 can be fastened by pressing it towards the buckle, thus preventing the filter 4 from falling off.

[0053] According to one embodiment of the present invention, the optical device adapted to the multi-wavelength scanning device includes two lenses 2, which are disposed at both ends of the housing 1. The optical device adapted to the multi-wavelength scanning device includes two mounting bases 3, two filters 4, and two magnetic components 5, with each mounting base 3, filter 4, and magnetic component 5 corresponding to one lens 2.

[0054] Understandably, lenses 2 are provided at both ends of the housing 1 for taking pictures. The two lenses 2 can work simultaneously. Depending on the working scenario, a filter 4 can be installed on one of the lenses 2, or both lenses 2 can be equipped with filters 4, increasing selectivity. Optionally, the optical device adapted to the multi-wavelength scanning equipment includes multiple lasers, which are installed between the two lenses 2.

[0055] The scanning device according to a second aspect of the present invention includes a body and the aforementioned optical device adapted to a multi-wavelength scanning device, wherein the optical device adapted to the multi-wavelength scanning device is disposed in the body.

[0056] The scanning device according to the present invention includes the optical device adapted to the multi-wavelength scanning device described above, and therefore has all the technical effects of the optical device adapted to the multi-wavelength scanning device described above, which will not be repeated here.

[0057] Finally, it should be noted that the above embodiments are only used to illustrate the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the embodiments, those skilled in the art should understand that various combinations, modifications, or equivalent substitutions of the technical solutions of the present invention do not depart from the spirit and scope of the technical solutions of the present invention and should be covered within the scope of the claims of the present invention.
