Embodiment Construction

[0107] 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.

[0108] 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 the object side are defined as the range through which the imaging ray passes, where the imaging ray includes the chief ray (chiefray) Lc and the marginal ray (marginalray) 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 ...

Abstract

The invention relates to an optical lens, particularly to an optical imaging lens and electronic device. The optical imaging lens includes fives lenses, and each lens has an object side face and an image side face; the image side face of the first lens has a concave surface part located in an area near the circumference; the object side face of the second lens has a convex surface part located in an area near the circumference, and the image side face of the second lens has a convex surface part located in an area near the circumference; the third lens is of a plastic material; the image side face of the fourth lens has a convex surface part located in an area near the circumference; and the object side face of the fifth lens has a concave surface part located in an area near the circumference, and (G12+G45)/T3>=1.5 and T3/G12<=1.1 are satisfied. The electronic device includes an enclosure, and an image module which includes the abovementioned imaging lens, a lens barrel, a module holder unit and an image sensor. The electronic device has good practical performance and has a structural design of being light, thin, short and small.

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 trend of thinner and lighter cameras also increases the demand for miniaturization of image modules. In order to reduce the size of the optical lens, the length of the optical lens installed in the image module needs to be shortened accordingly. However, in order to avoid the degradation of the photographic effect and quality, good optical performance must still be taken into account when shortening the length of the optical lens. However, the most important characteristics of optical lenses a...
