Specifically, the lens assembly of the camera head assembly may include a plurality of lenses, and any one of the lenses may be the camera lens 100 described in this application; specifically, in order to facilitate the formation of the infrared filtering film layer 120 and other structures on the surface of the lens body 110, a lens with a relatively flat outer surface in the lens assembly may be selected as the lens body 110, and the infrared filtering film layer 120 and other structures may be formed on the surface of the lens body.
According to some examples of the present application, the specific material, structure, and the like of the infrared filter film layer 120 are not particularly limited as long as they have a good infrared cut effect and do not affect the transmission of visible light. Specifically, the infrared filter layer 120 may be an optical coating structure formed on the surface of the lens body 110; specifically, the infrared filter layer 120 may include a plurality of first dielectric sublayers (not shown in the drawings) stacked together, and the first dielectric sublayers may include a first odd sublayer and a first even sublayer, wherein the first odd sublayer and the first even sublayer have different refractive indexes, so that the infrared filter layer 120 may better cut off infrared light through the first odd sublayer and the first even sublayer having different refractive indexes. Specifically, the material forming the first odd sub-layer at least comprises silicon dioxide and magnesium fluoride, and the material forming the first even sub-layer at least comprises titanium dioxide, trititanium pentoxide, zirconium dioxide and tantalum pentoxide. Thereby, the infrared cut effect of the infrared filter layer 120 is further improved.

For example, the total thickness of the infrared filter layer 120 may be 4 μm, may be 5 μm, may be 5.5 μm, and the like. The infrared filter film layer 120 having the thickness described above can cut off infrared light well, and does not affect the transmission of visible light.

From this, the infrared absorption performance and the ultraviolet absorption performance preferred of this optical cement layer 130 can further improve the infrared effect of cutting off of this camera lens 100 to make this camera lens 100 have the ultraviolet effect of cutting off, can further improve the shooting effect of camera subassembly. Specifically, the light transmittance of the optical adhesive layer 130 in the visible light band of 450-600nm may be not less than 88%, for example, may be 90%. Therefore, the optical adhesive layer 130 has a high light transmittance in the visible light band, so that the light transmittance of the camera lens 100 in the visible light band can be improved, and the shooting effect of the camera assembly using the camera lens 100 can be further improved.
According to some examples of the present application, the material forming the optical adhesive layer 130 is not particularly limited as long as it has infrared absorption properties. Specifically, the material forming the optical adhesive layer 130 may include: an ethylene oxide compound and a coloring compound that can adjust the absorption characteristics of the optical adhesive layer 130 to light, for example, by selecting an appropriate coloring compound, the optical adhesive layer 130 can have good infrared absorption performance and ultraviolet absorption performance. Specifically, the thickness range of the optical adhesive layer 130 may include 1-10 μm, for example, the thickness of the optical adhesive layer 130 may be 2 μm, may be 4 μm, may be 5 μm, may be 6 μm, may be 7 μm, may be 8 μm, may be 9 μm, and the like. Therefore, when the thickness of the optical adhesive layer 130 is within the above range, the infrared cut-off effect and the visible light transmittance of the camera lens 100 can be better improved, and the thickness of the camera lens 100 is not significantly increased, which is beneficial to the light and thin design of the camera assembly.
Specifically, as mentioned above, the infrared filter layer 120 may also be formed by an optical glue having an infrared absorption effect; specifically, the material forming the infrared filter film layer 120 and the material forming the optical adhesive layer 130 may be the same, that is, the components, the performance, and the like of the optical adhesive forming the infrared filter film layer 120 may be the same as those of the optical adhesive layer 130 described above, and are not described herein again. From this, all set up the rete that has the infrared effect of cutting off through the both sides at lens main part 100, can further improve this camera lens 100's infrared effect of cutting off.

According to some examples of the present application, the camera lens 100 further includes an antireflection film layer 140, and the antireflection film layer 140 is disposed on a side of the optical adhesive layer 130 away from the lens body 110. When the infrared filtering film layer 120 includes an optical coating structure, the antireflection film layer 140 can reduce the problem that the transmittance is affected due to the serious light reflection caused by the mismatch of refractive indexes of the infrared filtering film layer 120 and air; the antireflection film layer 140 can further improve the transmittance of the camera lens 100 in the visible light band, improve the shooting effect of the camera assembly, and protect the optical adhesive layer 130.
Specifically, the antireflection film layer 140 may include a plurality of second dielectric sublayers (not shown) stacked together, the second dielectric sublayers including a second odd-numbered sublayer and a second even-numbered sublayer, and the refractive indices of the second odd-numbered sublayer and the second even-numbered sublayer are different. Specifically, the material forming the second odd sub-layer at least comprises silicon dioxide and magnesium fluoride, and the material forming the second even sub-layer at least comprises titanium dioxide, trititanium pentoxide, zirconium dioxide and tantalum pentoxide. This further improves the light transmittance of the camera lens 100 in the visible light band. Specifically, the materials of the second odd-numbered sublayer and the second even-numbered sublayer can be selected through the design of an optical film system, and the like, and the number of layers, the thickness of the single layer, and the like of the second odd-numbered sublayer and the second even-numbered sublayer are adjusted, so that the finally formed antireflection film layer 140 has a better light transmittance in the visible light band. Specifically, the light transmittance of the antireflection film layer 140 in the visible light band may be not less than 98%. Specifically, the total thickness of the anti-reflection film layer 140 may range from 0.2 μm to 1 μm, for example, the total thickness of the anti-reflection film layer 140 may be 0.4 μm, may be 0.5 μm, may be 0.6 μm, may be 0.8 μm, and the like. Therefore, the antireflection film layer 140 with the above performance parameters can better reduce the problem that the transmittance is affected due to the serious light reflection caused by the mismatch of the refractive indexes of the infrared filtering film layer 120 and the air, so that the transmittance of the camera lens 100 in the visible light band can be further improved, and the shooting effect of the camera assembly can be improved.
