A schematic structural diagram of one of the portable electronic devices of the embodiment.

To further illustrate the various embodiments, the invention is provided with the drawings. The drawings are a part of the disclosure of the present invention, and are mainly used to explain the embodiments, and the operation of the embodiments may be explained in conjunction with the related description of the specification. With reference to such content, those of ordinary skill in the art should be able to understand other possible embodiments and advantages of the present invention. Elements in the figures are not drawn to scale, and similar elements are generally used to represent similar elements.

As used in this specification, "a lens having a positive refractive power (or a negative refractive power)" means that the refractive index of the lens on the optical axis calculated by Gaussian optical theory is positive (or negative). The image side and the object side are defined as a range in which the imaging light passes, wherein the imaging light includes a chiefray Lc and a marginal ray Lm, as shown in FIG. 1, I is an optical axis and the lens is The optical axis I is radially symmetric with respect to the axis of symmetry. The region on the optical axis passing through the optical axis is the region A near the optical axis, the region through which the edge light passes is the circumferential region C, and the lens further includes an extension E (ie, a radially outward region of the region C near the circumference for the lens to be assembled in an optical imaging lens, the ideal imaging light does not pass through the extension E, but the extension The structure and shape of E are not limited thereto, and the following embodiments omits part of the extension in order to simplify the drawing. More specifically, the method of determining the area near the surface or the optical axis, the area near the circumference, or the range of the plurality of areas is as follows: as shown in Fig. 1, it is a cross-sectional view in the radial direction of a lens. In the cross-sectional view, when determining the range of the region, a center point is defined as an intersection with the optical axis on the surface of the lens, and a transition point is a point on the surface of the lens, and the line passing through the point It is perpendicular to the optical axis. If there are a plurality of transition points outward in the radial direction, the first transition point and the second transition point are sequentially, and the transition point farthest from the optical axis in the effective half-effect path is the Nth transition point. The range between the center point and the first transition point is a region near the optical axis, and the radially outward region of the Nth transition point is a region near the circumference, and different regions can be distinguished according to the respective transition points. Further, the effective radius is the vertical distance at which the edge ray Lm intersects the lens surface to the optical axis I.

As shown in FIG. 2, the shape concavities and convexities of the region are determined on the image side or the object side by the intersection of the light rays (or the light ray extending lines) passing through the region in parallel with the optical axis (the light focus determination method). For example, when the light passes through the area, the light will be focused toward the image side, and the focus of the optical axis will be on the image side, such as the R point in FIG. 2, and the area is a convex surface. Conversely, if the light passes through the certain area, the light will diverge, and the extension line and the focus of the optical axis are on the object side. For example, at point M in Fig. 2, the area is a concave surface, so the center point is between the first transition point. The convex portion, the radially outward portion of the first switching point is a concave surface; as can be seen from FIG. 2, the switching point is a boundary point of the convex surface of the convex surface, so that the inner side of the region adjacent to the radial direction can be defined. The area has a different face shape with the transition point as a boundary. In addition, if the shape of the region near the optical axis is judged according to the judgment of the person in the field, the R value (referring to the radius of curvature of the paraxial axis, generally refers to the R on the lens data in the optical software). Value) Positive and negative judgment bump. In the aspect of the object, when the R value is positive, it is determined as a convex surface, and when the R value is negative, it is determined as a concave surface; on the image side, when the R value is positive, it is determined as a concave surface, when R is When the value is negative, it is determined as a convex surface, and the unevenness determined by this method is the same as the light focus determination method.

If there is no transition point on the surface of the lens, the area near the optical axis is defined as 0~50% of the effective radius, and the area near the circumference is defined as 50~100% of the effective radius.

3 is a view showing that the lens image side surface of the first example has only the first switching point on the effective radius, the first region is the vicinity of the optical axis, and the second region is the region near the circumference. The R value of the side of the lens image is positive, so that the area near the optical axis has a concave surface; the surface shape of the vicinity of the circumference is different from the inner area of the area immediately adjacent to the radial direction. That is, the area near the circumference and the area near the optical axis are different; the area near the circumference has a convex surface.

4 is a view showing the lens object side surface of the second example having first and second switching points on the effective radius, wherein the first region is a region near the optical axis, and the third region is a region near the circumference. The R value of the side surface of the lens object is positive, so that the area near the optical axis is determined to be a convex surface; the area between the first switching point and the second switching point (second area) has a concave surface, and the area near the circumference (third area) Has a convex face.

5 is a third example of the lens object side surface having no transition point on the effective radius. At this time, the effective radius 0% to 50% is the vicinity of the optical axis, and 50% to 100% is the vicinity of the circumference. Since the R value in the vicinity of the optical axis is positive, the side surface of the object has a convex portion in the vicinity of the optical axis; and there is no transition point between the vicinity of the circumference and the vicinity of the optical axis, so that the vicinity of the circumference has a convex portion.

The optical imaging lens of the present invention is a fixed-focus lens, and one of the first lens, the second lens, the third lens, and the fourth lens is sequentially disposed from the object side to the image side along an optical axis. A fifth lens is constructed, each lens having a refractive power and having an object side facing the object side and passing the imaging light and an image side facing the image side and passing the imaging light. The optical imaging lens of the present invention has only the aforementioned five lenses having refractive power, and provides a wide shooting angle and good optical performance by designing the detailed features of each lens.

The characteristics of the aforementioned lenses designed in this case mainly consider the optical characteristics of the optical imaging lens and the length of the lens. For example, forming a concave surface on the image side of the first lens in the vicinity of the optical axis can help collect imaging light. Forming a concave surface in the vicinity of the circumference on the image side surface of the second lens can achieve the effect of correcting the overall aberration, and can effectively correct the aberration of the partial imaging of the object. Further, a concave surface portion formed in a region near the optical axis on the object side surface of the third lens, a convex portion forming a circumferential vicinity region on the object side surface of the fourth lens, and a concave surface forming a circumferential vicinity region on the image side surface of the fourth lens are further provided. The department can achieve the effect of improving the image quality.
