BACKGROUND

In the field of photography, a telephoto lens has irreplaceable advantages in telephotographing and detail capturing. In recent years, telephoto lenses have been used for more and more mobile phones to achieve relatively high spatial angular resolutions so as to enhance high-frequency information in combination with image fusion technologies. As a portable electronic device, a mobile phone has relatively high requirements on a size and imaging of a telephoto lens.

DETAILED DESCRIPTION OF THE EMBOCIMENTS

It is to be noted that the embodiments in the disclosure and features in the embodiments may be combined without conflicts. The disclosure will be described below with reference to the drawings and in combination with the embodiments in detail.

It is to be pointed out that, unless otherwise specified, all technical and scientific terms used in the disclosure have the same meanings as commonly understood by those of ordinary skill in the art of the disclosure.

In the disclosure, unless conversely specified, the used orientation terms “upper, lower, top, and bottom” are usually for the directions shown in the drawings, or for a component in a vertical, perpendicular, or gravity direction. Similarly, for convenient understanding and description, “inner and outer” refer to inner and outer relative to a contour of each component. However, these orientation terms are not intended to limit the disclosure.

It should be noted that, in this description, expressions first, second, third and the like are only used to distinguish one feature from another feature and do not represent any limitation to the feature. Thus, a first lens discussed below could also be referred to as a second lens or a third lens without departing from the teachings of the disclosure.

In the drawings, the thickness, size and shape of the lens have been slightly exaggerated for ease illustration. In particular, a spherical shape or aspheric shape shown in the drawings is shown by some embodiments. That is, the spherical shape or the aspheric shape is not limited to the spherical shape or aspheric shape shown in the drawings. The drawings are by way of example only and not strictly to scale.

Herein, a paraxial region refers to a region nearby an optical axis. If a lens surface is a convex surface and a position of the convex surface is not defined, it indicates that the lens surface is a convex surface at least in the paraxial region, and if a lens surface is a concave surface and a position of the concave surface is not defined, it indicates that the lens surface is a concave surface at least in the paraxial region. A surface, close to an object side, of each lens is called an object-side surface of the lens, and a surface, close to an image side, of each lens is called an image-side surface of the lens. A surface type of the paraxial region may be judged according to a judgment manner known to those of ordinary skill in the art, and whether a surface is concave or convex is judged according to whether an R value is positive or negative (R refers to a curvature radius of the paraxial region, usually refers to an R value on lens data in optical software). For example, an object-side surface is determined as a convex surface if the R value is positive, and is determined as a concave surface if the R value is negative. An image-side surface is determined as a concave surface if the R value is positive, and is determined as a convex surface is the R value is negative.

The disclosure is mainly intended to provide an optical imaging lens assembly, so as to solve the problem in the related art that an optical imaging lens assembly may not have all of long focal length, ultra-thin performance and high resolution at the same time.

The optical imaging lens assembly of the disclosure may adopt multiple lenses, for example, the above-mentioned five. The refractive powers and surface types of each lens, the center thicknesses of each lens, on-axis distances between the lenses and the like may be reasonably configured to effectively enlarge an aperture of the optical imaging lens assembly, reduce a sensitivity of the lens, improve a machinability of the lens, and ensure that the optical imaging lens assembly is more favorable for production and machining and applicable to a portable electronic device. The optical imaging lens assembly also has the advantages of large aperture, ultra-thin design and high imaging quality, and may satisfy a miniaturization requirement of an intelligent electronic product. In addition, a large-aperture design may achieve a higher luminous flux so as to reduce an optical aberration in low light and improve an image acquisition quality to achieve a stable imaging effect.

In the disclosure, at least one of mirror surfaces of the lenses is an aspheric mirror surface. An aspheric lens has a feature that a curvature keeps changing from a center of the lens to a periphery of the lens. Unlike a spherical lens with a constant curvature from a center of the lens to a periphery of the lens, the aspheric lens has a better curvature radius feature and the advantages of improving distortions and improving astigmatism aberrations. With the adoption of the aspheric lens, astigmatism aberrations during imaging may be eliminated as much as possible, thereby improving the imaging quality.

However, those skilled in the art should know that the number of the lenses forming the optical imaging lens assembly may be changed without departing from the technical solutions claimed in the disclosure to achieve each result and advantage described in the specification. For example, although descriptions are made in the embodiments with five lenses as an example, the optical imaging lens assembly is not limited to five lenses. If necessary, the optical imaging lens assembly may further include another number of lenses.

In the example, each lens may use an aspheric lens, and a surface type x of each aspheric surface is defined through the following formula:

$\begin{matrix} x = \frac{{ch}^{2}}{1 + \sqrt{1 - (k + 1) c^{2} h^{2}}} + \sum ai ? & Formula (1) \end{matrix}$

$? indicates text missing or illegible when filed$

wherein x is a vector height of a distance between the aspheric surface and a vertex of the aspheric surface when the aspheric surface is located at a position with the height h in an optical axis direction, c is a paraxial curvature of the aspheric surface, c=1/R (namely, the paraxial curvature c is a reciprocal of the curvature radius R in Table 1 above), k is a conic coefficient (specified in Table 1); and Ai is a correction coefficient of the i-th order of the aspheric surface.

Table 2 shows high-order coefficients that may be used for each aspheric surface of each aspheric lens in the example.
