Embodiment Construction

[0123] Before the present invention is described in detail, it should be noted that in the following description, similar components are denoted by the same numerals.

[0124] The term "a lens has positive (or negative) refractive power" in this specification refers to the positive (or negative) refractive power of the lens on the optical axis calculated by Gaussian optics theory. The image side and object side are defined as the range through which the imaging light passes, where the imaging light includes the chief ray Lc and the marginal ray Lm, such as figure 1 As shown, I is the optical axis and this lens is radially symmetrical to each other with the optical axis I as the symmetry axis. The area where the light rays pass through the optical axis is the area A near the optical axis, and the area where the marginal light rays pass is the area C near the circumference. , In addition, the lens also includes an extension E (that is, the area near the circumference C radially ...

Abstract

The present invention relates to an optical imaging lens and an electronic device using the optical imaging lens. The optical imaging lens includes five lenses. The image side of the first lens has a convex surface located in the vicinity of the optical axis; the image side of the second lens has a concave portion located in the vicinity of the circumference; the object side of the third lens has a concave portion located in the vicinity of the circumference; the fourth lens has a negative refractive power, and the object side of the fourth lens has a convex surface located in the vicinity of the optical axis portion; and the object side of the fifth lens has a convex portion located in the vicinity of the circumference, and satisfies (T2+T4) / G45≦2.9. The electronic device of the present invention includes a casing and an image module. The image module includes an optical imaging lens, a lens barrel, a module rear seat unit, and an image sensor. The invention has both good practical performance and contributes to light, thin and small structural design.

Description

technical field [0001] The invention relates to an optical lens, in particular to an optical imaging lens and an electronic device using the optical imaging lens. Background technique [0002] In recent years, the popularization of portable electronic products such as mobile phones and digital cameras has led to the vigorous development of imaging module related technologies. The imaging module mainly includes components such as optical imaging lens, module holder unit and sensor. The thin and light trend of digital cameras also makes the miniaturization of image modules more and more demanding. For the technological progress and size reduction of CMOS), the length of the optical imaging lens loaded in the image module also needs to be shortened accordingly. performance. Therefore, the most important characteristics of optical imaging lenses are nothing more than imaging quality and volume. [0003] However, the design of optical imaging lens is not simply to scale down t...
