Embodiment Construction

[0117] 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.

[0118] The expression "a lens has positive refractive power (or negative refractive power)" in this specification means that the lens has positive refractive power (or negative refractive power) in the vicinity of the optical axis. "The object side (or image side) of a lens has a convex surface (or concave surface) located in a certain area" means that the area is closer to the direction parallel to the optical axis than the radially outer area of ​​the area. For "convex" (or "concave"), the figure 1 For example, where I is the optical axis and the lens is radially symmetrical to each other with the optical axis I as the axis of symmetry, the object side of the lens has a convex surface in the A region, a concave surface in the B region, and a convex surface in the C region , the reason is that compared with t...

Abstract

The invention relates to an optical imaging lens and an electronic device using the optical imaging lens. The optical imaging lens of the present invention comprises five lenses sequentially from the object side to the image side, the image side of the first lens has a convex portion located in the vicinity of the circumference, the object side of the second lens has a convex portion located in the vicinity of the circumference and The image side has a concave portion located in the vicinity of the optical axis, the image side of the third lens has a concave portion located in the vicinity of the circumference, the object side of the fourth lens has a concave portion located in the vicinity of the optical axis, and the fifth lens has a concave portion located in the vicinity of the optical axis. The image side of the lens has a concave portion located in the vicinity of the optical axis, and satisfies ALT / G34≦7.7. The camera device of the present invention includes a casing, an image module including the above-mentioned optical imaging lens, a lens barrel, a module rear seat unit, and an image sensor. Therefore, the present invention can shorten the lens length and maintain good imaging quality.

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. [0003] U.S. Patent Publication Nos. 20110316969, 20100254029, 20130107376, 20130057967, U.S. Patent Publication Nos. 8,345,323, 7,911,712, and Japanese Patent Publication No. 2008-281760 all disclose an ...
