Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. It is to be understood that the embodiments described are only a few embodiments of the present application and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without inventive step, are within the scope of the present application.

An embodiment of the present application provides a lens, please refer to fig. 1, and fig. 1 is a schematic structural diagram of the lens provided in the embodiment of the present application. The lens 100 includes a lens barrel 160 and one or more purple fringing lenses 120, the one or more purple fringing lenses 120 are mounted in the lens barrel 160, and the purple fringing lenses 120 can block at least part of blue-violet light and/or at least part of red light from passing through the purple fringing lenses 120.

It can be understood that blue-violet light and red light in an optical signal transmitted through the lens can cause a purple fringing phenomenon of rear-end imaging, and in the related art, there are two main schemes for solving the purple fringing phenomenon, one is to optimize chromatic aberration of an imaging system of the camera module during design, but this method generally increases difficulty and cost for forming the lens in the camera module; another approach is to algorithmically handle the purple-fringing phenomenon, but this approach can result in loss of detail and color in the region with the purple-fringing phenomenon.

In this embodiment, the purple fringing mirror 120 in the lens 100 may directly block at least part of the blue-violet light and/or at least part of the red light, and the purple fringing mirror 120 may directly reduce the blue-violet light and/or the red light from passing through the lens 100, thereby improving the purple fringing phenomenon imaged according to the light signal passing through the lens 100. Compare in the colour difference of the imaging system who optimizes the module of making a video recording, the purple fringing phenomenon structure is succinct is improved through purple fringing lens 120 to this embodiment, realizes that the degree of difficulty is low. In addition, compared with processing the purple fringing phenomenon through an algorithm, in the present embodiment, the purple fringing elimination lens 120 in the lens 100 directly blocks part of blue-violet light and/or part of red light causing the purple fringing phenomenon, and meanwhile, does not block other light signals required for imaging, and the back-end imaging does not lose part of details and colors due to the purple fringing phenomenon.

It should be noted that the purple fringing elimination lens 120 can block part of blue-violet light and/or part of red light causing the purple fringing phenomenon, thereby improving the purple fringing phenomenon of the back-end imaging. Of course, in some other embodiments, the purple-fringing mirror 120 can block all blue-violet light and/or all red light, but some color light signals (such as red light) are lost, and the back-end imaging needs to be compensated by an algorithm or other light signals acquired by the lens 100 to obtain better image quality. In other embodiments, the purple-fringing mirror 120 may also block all blue-violet light and/or part of red light, or the purple-fringing mirror 120 may also block part of blue-violet light and/or all of red light, and the back-end imaging also needs to be compensated by an algorithm or by optical signals acquired by other lenses 100.

The purple-fringing lens 120 may block at least part of the blue-violet light and/or at least part of the red light in such a way that the purple-fringing lens 120 absorbs at least part of the blue-violet light and/or at least part of the red light.

In particular, the purple-fringed lens 120 capable of absorbing at least a portion of blue-violet light and/or at least a portion of red light may be implemented by the pigment material it comprises. Referring to fig. 2, fig. 2 is a schematic view of a first structure of a purple fringing lens in the lens barrel shown in fig. 1. The purple-edged lens 120 includes a base component 122 and a pigment component 124, the pigment component 124 being dispersed between the base component 122, the pigment component 124 being capable of absorbing at least a portion of blue-violet light and/or at least a portion of red light. The pigment component 124 is dispersed between the base material components 122. it is understood that the purple fringed lens 120 is formed by a corresponding process after mixing the pigment material and the base material, the purple fringed lens 120 includes the pigment component 124 corresponding to the pigment material and the base material component 122 corresponding to the base material, the pigment component 124 is dispersed in the base material component 122, the base material component 122 is also dispersed in the pigment component 124, and the pigment component 124 and the base material component 122 are intermingled and mixed.

The pigment material may be dispersed in the base material component 122, and may be implemented in other structures. Referring to fig. 3, fig. 3 is a second structural diagram of a purple fringing lens in the lens barrel shown in fig. 1. The purple fringed lens 120 includes a substrate 126 and a film 128, the film 128 covers the substrate 126, the film 128 may be formed of a pigment material, and the film 128 may absorb blue-violet light and/or red light. For example, a pigment material may be sprayed onto the substrate 126 to form the film 128, and the film 128 may absorb at least some of the blue-violet light and/or at least some of the red light that may cause purple fringing. The film 128 may cover the entire substrate 126. The thin film 128 may be formed only of a pigment material, or may be formed by mixing a pigment material with another material, and the embodiment is not limited to the form of the thin film 128 formed of a pigment material.

Referring to fig. 4, fig. 4 is a corresponding schematic diagram of wavelengths and transmittances of optical signals corresponding to different lenses according to the embodiment of the present application, in which a curve L1 is a corresponding curve of wavelengths and transmittances of optical signals corresponding to a common lens, a curve L2 is a corresponding curve of wavelengths and transmittances of optical signals corresponding to a purple fringing lens, an abscissa of the graph is the wavelength of an optical signal, and an ordinate of the graph is the transmittance. The purple fringing lens 120 can have a maximum absorption peak at a wavelength between 700 nanometers and 760 nanometers. The purple fringing lens 120 can absorb red light and has a maximum absorption peak between wavelengths of 700 nanometers to 760 nanometers. The maximum absorption peak of the purple fringing mirror 120 can be adjusted according to the wavelength of the optical signal with the most serious purple fringing phenomenon formed by the lens 100, and the adjustment of the maximum absorption peak of the purple fringing mirror 120 can be realized by adjusting the doping proportion of the pigment material and the like. For example, the wavelength of the optical signal with the most severe purple fringing phenomenon formed by the lens 100 is 700nm, the purple fringing lens 120 is set to have the maximum absorption peak at the wavelength of 700nm, so that the transmittance of the optical signal with the wavelength of 700nm through the purple fringing lens 120 is lower than a preset threshold, and the preset threshold can be set as required, for example, the preset threshold can be 10%, 15%, 20%, and the like. It is understood that in other embodiments, the purple fringing lens 120 can have maximum absorption peaks at other wavelengths, such as 710 nm, 720 nm, etc.

In the visible light range, the wavelength corresponding to T50 (transmittance of 50%) of the lens in the related art is generally 400 nm. The purple fringing lens of the embodiment has a wavelength corresponding to a transmittance of 50% between 400 nanometers and 430 nanometers, so that the wavelength corresponding to a transmittance of 50% of the lens is also between 400 nanometers and 430 nanometers. For example, the T50 (transmittance is 50%) of the anti-purple fringing lens or lens of the embodiment may have a wavelength of 420 nm or 430nm, so as to reduce the transmittance of blue-violet light and reduce the purple fringing phenomenon.

The purple fringing lens 120 of the embodiment has a wavelength corresponding to a transmittance of 50% of 400nm to 430nm, so that the wavelength corresponding to a transmittance of 50% of the lens 100 is also 400nm to 430 nm. For example, the wavelength corresponding to T50 (transmittance is 50%) of the anti-purple fringing lens 120 or the lens 100 of the embodiment may be 420 nm or 430nm, so as to reduce the blue-violet transmittance and reduce the purple fringing phenomenon.

It should be noted that the purple fringed lens 120 in this embodiment can achieve the above function by adding a pigment material. That is, the purple-fringed lens 120 having a pigment material may absorb at least a portion of the blue-violet light and at least a portion of the red light. For example, the wavelength corresponding to T50 (transmittance 50%) without the added pigment material is 400nm, and the wavelength corresponding to T50 (transmittance 50%) of the purple fringed lens 120 with the added pigment material or the lens 100 with the purple fringed lens 120 is shifted from 400nm to around 430nm, and the transmittance at 700nm is as low as 10%. The pigment material may be selected as needed, and for example, a pigment material sold by JSR corporation under the trade name D4000 may be selected. Of course, the purple fringing lens 120 in this embodiment can also achieve the above-mentioned functions by adding a plurality of pigment materials. For example, the purple fringing lens 120 shifts the wavelength corresponding to T50 (transmittance 50%) of the purple fringing lens 120 or lens 100 from 400nm to around 430nm by adding the first pigment material, and the purple fringing lens 120 has a transmittance as low as 10% at 700nm by adding the second pigment material. Wherein, the first pigment material and/or the second pigment material can be replaced by other pigment materials after being mixed. In addition, the purple-fringed lens 120 can also absorb at least a portion of the blue-violet light or absorb at least a portion of the red light by adding one or more pigment materials.

The substrate 126 of the purple fringed lens 120 can also be selected as desired, for example, the substrate 126 can be a glass substrate 126 or a resin substrate 126. The material of the substrate 126 can also be selected according to the requirement, for example, the material of the substrate 126 can be a glass material or a resin material.

It should be noted that the doping ratio of the pigment material may be reasonably set as required, and if the doping ratio of the pigment material is too high, the transmittance of the purple fringing mirror 120 at 430nm to 680 nm may be reduced, so as to reduce the effective imaging light flux entering the image sensor. Therefore, the mass ratio of the pigment component to the base material in the purple fringing lens 120 is less than 1:9, which not only can well improve the purple fringing phenomenon, but also can make the purple fringing lens 120 have better transmittance. For example, if there is only one purple fringing lens 120 in the lens 100, the doping ratio of the pigment material in the purple fringing lens 120 may be high, and the doping ratio may be 8% or 10%, and the doping ratio of the pigment material refers to the ratio of the mass of the pigment material to the total mass of the purple fringing lens. If there are a plurality of purple boundary elimination lenses 120 in the lens 100, the doping ratio of the pigment material in each purple boundary elimination lens 120 may be low, and the doping ratio may be 5% or 6%. It should be noted that the lens 100 may only include the purple fringing lens 120, and in some other embodiments, as shown in fig. 5, the lens 100 includes, in addition to the purple fringing lens 120, other normal lenses 140, and the other normal lenses 140 do not block the blue-violet light and the red light from passing through.

It should be noted that, in some embodiments, the lens may be applied to a camera module, the camera module further includes an image sensor, and blue glass may be further disposed on a side of the lens facing the image sensor, where the blue glass is used to filter invisible light, such as infrared light and ultraviolet light. In the related art, a filter layer is added on the blue glass by spin coating to filter out part of infrared to improve the purple fringing phenomenon. The purple fringing lens in the embodiment can directly filter out red light and/or blue-violet light causing purple fringing phenomenon, and does not need to carry out special treatment on blue glass. In addition, the purple fringing phenomenon is generated by the lens, the purple fringing eliminating pigment material is placed in the lens of the lens to have a better effect on the purple fringing elimination, and the purple fringing phenomenon can be solved from the source.

Optionally, a material for filtering invisible light may be added to the lens (such as a purple fringing lens) of the lens to filter invisible light such as infrared light and ultraviolet light, so as to cancel the setting of blue glass and simplify the structure of the camera module.

Optionally, with continued reference to fig. 1 to 5, the purple-fringing mirror 120 may block at least part of the blue-violet light and/or at least part of the red light in such a manner that the purple-fringing mirror 120 reflects at least part of the blue-violet light and/or at least part of the red light. Illustratively, the deco-mirror plate 120 is formed by doping the material of the substrate 126 with a reflective material by which at least a portion of the blue-violet light and/or at least a portion of the red light is reflected, thereby reducing the transmission of blue-violet light and/or red light through the deco-mirror plate 120. In another example, a reflective film may be disposed on the substrate 126 to form the piping lens 120, and the reflective film may be capable of reflecting blue-violet light and/or red light to reduce the blue-violet light and/or red light transmitted through the piping lens 120. The purple fringing lens 120 in this embodiment does not greatly affect the transmittance of other visible light, that is, does not affect the rear end of the image formed by the optical signal transmitted through the purple fringing lens 120.

Referring to fig. 1, the outer surface of the lens barrel 160 may be provided with a thread structure, and the coil motor may drive the lens barrel 160 to move and drive the lens in the lens barrel 160 to move through the thread structure, so as to implement the focusing function. Illustratively, a purple fringing lens and a plurality of common lenses are arranged in the lens barrel, the coil motor drives the lens barrel to move, and the lens barrel drives the purple fringing lens and the common lenses to move, so that the focusing of the purple fringing lens and the common lenses is realized. Of course, the outer surface of the lens barrel may not be provided with a screw structure as required.
