[0028] For a better understanding of the present application, various aspects of the present application will be described in more detail with reference to the accompanying drawings. It should be understood that these detailed descriptions are merely descriptions of exemplary embodiments of the present application and are not intended to limit the scope of the present application in any way. Throughout the specification, the same reference numerals refer to the same elements. The expression "and / or" includes any and all combinations of one or more of the associated listed items.

[0029] It should be noted that in this specification, the terms "first," "second," "third," etc., are used solely to distinguish one feature from another and do not limit the features. Thus, the first lens discussed below could also be referred to as the second lens or the third lens without departing from the teachings of this application.

[0030] In the drawings, the thickness, size, and shape of the lenses are slightly exaggerated for ease of illustration.

[0031] In this article, the paraxial region refers to the area near the optical axis. If a lens surface is convex and the location of the convex surface is undefined, it means that the lens surface is convex at least in the paraxial region. If a lens surface is concave and the location of the concave surface is undefined, it means that the lens surface is concave at least in the paraxial region. The surface of each lens closest to the subject is called the object-side surface of the lens, and the surface of each lens closest to the imaging plane is called the image-side surface of the lens.

[0032] It should also be understood that the terms "comprises," "including," "having," "includes," and / or "comprising," when used in this specification, indicate the presence of the stated features, elements, and / or components, but do not preclude the presence or addition of one or more other features, elements, components, and / or combinations thereof. In addition, when expressions such as "at least one of..." appear after a list of listed features, they modify the entire list of features rather than modifying the individual elements in the list. In addition, when describing embodiments of the present application, "may" is used to mean "one or more embodiments of the present application." And, the term "exemplary" is intended to refer to an example or illustration.

[0033] Unless otherwise defined, all terms used herein (including technical and scientific terms) have the same meaning as commonly understood by those skilled in the art to which this application belongs. It should also be understood that terms (such as those defined in commonly used dictionaries) should be interpreted as having a meaning consistent with their meaning in the context of the relevant technology and will not be interpreted in an idealized or overly formal sense unless expressly defined as such herein.

[0034] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0035] The features, principles and other aspects of the present application are described in detail below.

[0036] An optical imaging lens assembly according to an exemplary embodiment of the present application may include a prism and, for example, six lenses having optical power, namely, a first lens, a second lens, a third lens, a fourth lens, a fifth lens, and a sixth lens. The prism may be configured such that light incident on the prism along the Y optical axis is reflected and then emitted from the prism along the X optical axis, where the X optical axis is perpendicular to the Y optical axis. The first through sixth lenses may be arranged sequentially along the X optical axis from the prism to the image side. Among the first through sixth lenses, any two adjacent lenses may have an air gap between them.

[0037] In an exemplary embodiment, the first lens may have positive optical power; the second lens may have negative optical power; the third lens may have positive or negative optical power, and its object-side surface may be convex and its image-side surface may be concave; the fourth lens may have positive or negative optical power, and its object-side surface may be concave and its image-side surface may be convex; the fifth lens may have positive or negative optical power, and its object-side surface may be convex; and the sixth lens may have positive or negative optical power. By properly controlling the positive and negative distribution of the optical power of each component of the system and the lens surface curvature, the low-order aberrations of the control system can be effectively balanced.

[0038] In an exemplary embodiment, the optical imaging lens assembly of the present application may satisfy the conditional equation TTL / f < 1, where TTL is the distance along the optical axis from the object-side surface of the first lens element to the imaging plane of the optical imaging lens assembly, and f is the total effective focal length of the optical imaging lens assembly. More specifically, TTL and f may further satisfy 0.8 < TTL / f < 0.9. When the optical imaging lens assembly satisfies TTL / f < 1, it can achieve telephoto characteristics.

[0039] In an exemplary embodiment, the optical imaging lens assembly of the present application may satisfy the conditional equation 2.4 < f1 / CT1 < 3.1, where f1 is the effective focal length of the first lens element, and CT1 is the center thickness of the first lens element along the optical axis. More specifically, f1 and CT1 may further satisfy 2.46 ≤ f1 / CT1 ≤ 3.09. If the focal power of the first lens element is too large, it can easily lead to significant fluctuations in the optical path and even produce a lens shape that is difficult to manufacture. Properly controlling the focal power of the first lens element can prevent excessive focal power from being borne by the first lens element and improve the manufacturability of the lens.

[0040] In an exemplary embodiment, the optical imaging lens system of the present application may satisfy the conditional equation: -1.5 < f2 / f1 < -1, where f2 is the effective focal length of the second lens element and f1 is the effective focal length of the first lens element. More specifically, f2 and f1 may further satisfy -1.44 ≤ f2 / f1 ≤ -1.08. When the first lens element has a negative focal power, ensuring the second lens element has a positive focal power effectively controls the size of the optical system and improves performance. Having focal powers of different signs on the first and second lenses enables the optical system to better balance aberrations.

[0041] In an exemplary embodiment, the optical imaging lens system of the present application may satisfy the conditional equation -1.0 < f6 / f < -0.5, where f6 is the effective focal length of the sixth lens element, and f is the total effective focal length of the optical imaging lens system. More specifically, f6 and f may further satisfy -0.85 ≤ f6 / f ≤ -0.52. This conditional equation of -1.0 < f6 / f < -0.5 helps increase the focal length of the system, achieving telephoto characteristics, and facilitates the ability to adjust the position of light, shortening the overall length of the optical imaging lens system. Optionally, the sixth lens element has negative focal power.

[0042] In an exemplary embodiment, the optical imaging lens group of the present application may satisfy the conditional formula 1.5<R4 / R5<3.0, wherein R4 is the radius of curvature of the image side surface of the second lens, and R5 is the radius of curvature of the object side surface of the third lens. More specifically, R4 and R5 may further satisfy 1.67≤R4 / R5≤2.52. The radius of curvature R4 of the image side surface of the second lens and the radius of curvature R5 of the object side surface of the third lens satisfy 1.5<R4 / R5<3.0, which helps to reduce the optical focal length of the image side lens of the optical system, so that the optical system has a better ability to balance chromatic aberration and distortion. Optionally, the image side surface of the second lens is concave, and the object side surface of the third lens is convex.

[0043] In an exemplary embodiment, the optical imaging lens assembly of the present application can satisfy the conditional equation 0.5 < R7 / R8 ≤ 1.5, where R7 is the radius of curvature of the object-side surface of the fourth lens element, and R8 is the radius of curvature of the image-side surface of the fourth lens element. More specifically, R7 and R8 can further satisfy 0.96 ≤ R7 / R8 ≤ 1.47. Properly allocating the ratio of the radius of curvature of the image-side surface of the fourth lens element to the radius of curvature of the object-side surface of the fourth lens element allows the imaging lens to better match the chief ray angle of the chip, thereby improving the imaging quality of the imaging lens assembly.

[0044] In an exemplary embodiment, the optical imaging lens assembly of the present application may satisfy the conditional formula 1.5<R11 / R12<3.0, wherein R11 is the radius of curvature of the object-side surface of the sixth lens, and R12 is the radius of curvature of the image-side surface of the sixth lens. More specifically, R11 and R12 may further satisfy 1.62≤R11 / R12≤2.68. Reasonable control of the ratio of the radius of curvature of the image-side surface of the sixth lens in the optical imaging lens assembly to the radius of curvature of the object-side surface of the sixth lens can effectively improve the chromatic aberration and distortion of the optical imaging lens assembly. Optionally, the object-side surface of the sixth lens is convex, and the image-side surface of the sixth lens is concave.

[0045] In an exemplary embodiment, the optical imaging lens assembly of the present application may satisfy the conditional equation 3.0 < CT1 / (CT2+CT3) < 3.5, where CT1 is the center thickness of the first lens on the optical axis, CT2 is the center thickness of the second lens on the optical axis, and CT3 is the center thickness of the third lens on the optical axis. More specifically, CT1, CT2, and CT3 may further satisfy 3.08 ≤ CT1 / (CT2+CT3) ≤ 3.39. The optical imaging lens assembly satisfying 3.0 < CT1 / (CT2+CT3) < 3.5 can effectively reduce the size of the system's backend, avoid excessive volume of the optical system lens assembly, reduce the difficulty of lens assembly, and achieve high space utilization.

[0046] In an exemplary embodiment, the optical imaging lens assembly of the present application may satisfy the conditional equation 6.0 < T34 / (T12 + T23 + T45 + T56) < 10.1, where T34 is the air distance between the third and fourth lenses on the optical axis, T12 is the distance between the first and second lenses on the optical axis, T23 is the air distance between the second and third lenses on the optical axis, T45 is the distance between the fourth and fifth lenses on the optical axis, and T56 is the distance between the fifth and sixth lenses on the optical axis. More specifically, T34, T12, T23, T45, and T56 may further satisfy 6.30 ≤ T34 / (T12 + T23 + T45 + T56) ≤ 10.04. The optical imaging lens group satisfies 6.0<T34 / (T12+T23+T45+T56)<10.1, which can ensure sufficient spacing between lenses, thereby allowing greater freedom of lens surface change, thereby improving the system's ability to correct astigmatism and field curvature.

[0047] In an exemplary embodiment, the optical imaging lens system may further include at least one aperture. The aperture may be positioned appropriately as needed, for example, between the prism and the first lens element. Optionally, the optical imaging lens system may further include a filter for correcting color deviation and / or a protective glass for protecting the photosensitive element located on the imaging surface.

[0048] The optical imaging lens system according to the above-described embodiment of the present application can utilize multiple lenses, such as the six lenses described above. By rationally allocating the focal power, surface shape, center thickness of each lens, and on-axis spacing between lenses, the imaging system can be effectively reduced in size, its sensitivity can be lowered, and its manufacturability can be improved, making the optical imaging lens system more amenable to production and suitable for portable electronic products. Placing a prism in front of the first lens can change the orientation of the lenses, allowing for a longer overall optical length without compromising device miniaturization.

[0049] In an embodiment of the present application, at least one of the mirror surfaces of each lens is an aspherical mirror surface, that is, at least one of the object side surface of the first lens to the image side surface of the sixth lens is an aspherical mirror surface. The characteristic of an aspherical lens is that the curvature changes continuously from the center of the lens to the periphery of the lens. Unlike a spherical lens with a constant curvature from the center of the lens to the periphery of the lens, an aspherical lens has a better curvature radius characteristic, and has the advantages of improving distortion aberration and improving astigmatism aberration. After adopting an aspherical lens, the aberration that occurs during imaging can be eliminated as much as possible, thereby improving the imaging quality. Optionally, at least one of the object side surface and the image side surface of each lens in the first lens, the second lens, the third lens, the fourth lens, the fifth lens and the sixth lens is an aspherical mirror surface. Optionally, the object side surface and the image side surface of each lens in the first lens, the second lens, the third lens, the fourth lens, the fifth lens and the sixth lens are all aspherical mirror surfaces.

[0050] However, those skilled in the art will appreciate that the number of lenses comprising the optical imaging lens system can be varied to achieve the various results and advantages described herein without departing from the claimed technical solutions. For example, while six lenses are described in the embodiments, the optical imaging lens system is not limited to six lenses. If desired, the optical imaging lens system can also include other numbers of lenses.

[0051] Specific embodiments of the optical imaging lens assembly applicable to the above-mentioned embodiments will be further described below with reference to the accompanying drawings.

[0052] Example 1

[0054] like Figure 1 As shown, the optical imaging lens group includes, from the object side to the image side along the optical axis, a prism, an aperture STO, a first lens E1, a second lens E2, a third lens E3, a fourth lens E4, a fifth lens E5, a sixth lens E6, a filter E7 and an imaging surface S15.

[0055] The prism allows light incident along the Y-axis to be reflected and then exit the prism along the X-axis. The first lens E1 has positive power, with its object-side surface S1 being convex and its image-side surface S2 being concave. The second lens E2 has negative power, with its object-side surface S3 being concave and its image-side surface S4 being concave. The third lens E3 has positive power, with its object-side surface S5 being convex and its image-side surface S6 being concave. The fourth lens E4 has positive power, with its object-side surface S7 being concave and its image-side surface S8 being convex. The fifth lens E5 has positive power, with its object-side surface S9 being convex and its image-side surface S10 being concave. The sixth lens E6 has negative power, with its object-side surface S11 being convex and its image-side surface S12 being concave. The filter E7 has an object-side surface S13 and an image-side surface S14. Light from an object sequentially passes through surfaces S1 to S14 and is ultimately imaged on an imaging surface S15.
