Embodiment Construction

[0110] The foregoing and other technical contents, features and effects of the present invention will be clearly presented in the following detailed description of several preferred embodiments with reference to the accompanying drawings.

[0111] Before the present invention is described in detail, it is to be noted that in the following description, similar components are denoted by the same reference numerals.

[0112] see figure 1 and image 3 , a first preferred embodiment of the optical imaging lens 10 of the present invention includes a first lens 3, an aperture 2, a second lens 4, and a third lens in sequence along an optical axis I from the object side to the image side 5. A fourth lens 6, and a filter 7. When the light emitted by an object to be photographed enters the optical imaging lens 10, and passes through the first lens 3, the aperture 2, the second lens 4, the third lens 5, the fourth lens 6, and the filter After the light sheet 7, an image is formed on an...

Abstract

The invention relates to a portable electronic device and an optical imaging lens thereof. The optical imaging lens sequentially comprises a first lens, a second lens, a third lens and a fourth lens from an object side to an image side, wherein each lens comprises an object side and an image side; the first lens is a lens with positive refractive index, and the object side and the image side of the first lens are respectively provided with a convex part positioned in the zone close to an optical axis; the object side of the second lens is provided with a convex part positioned in the zone close to the optical axis, and the image side of the second lens is provided with a concave part positioned in the zone close to the optical axis; the object side of the fourth lens is provided with a concave part positioned in the zone close to the optical axis; and the optical imaging lens can fulfill the condition expression that EFL / CT1 is more than or equal to 5.30. The portable electronic device comprises a frame and an imaging module arranged in the frame, wherein the imaging module comprises an optical imaging lens, a lens cone, a module pedestal unit and an image sensor. The lens still has an excellent optical performance when the length is shortened.

Description

technical field [0001] The present invention relates to an optical lens, in particular to a portable electronic device and an optical imaging lens thereof. Background technique [0002] In recent years, the popularity of portable electronic products such as mobile phones and digital cameras has led to the vigorous development of technologies related to image modules (mainly including optical imaging lenses, module holder units and sensors). The trend of thin and lightweight cameras also increases the demand for the miniaturization of image modules. With the development of charge coupled device (CCD) or complementary metal-oxide semiconductor (CMOS) ) technology progress and size reduction, the optical imaging lens loaded in the image module also needs to be shortened in length accordingly, but in order to avoid the degradation of photographic effect and quality, it is still necessary to take into account good optical performance when shortening the length of the optical imag...
