Embodiment Construction

[0092] To further illustrate the various embodiments, the present invention is provided with accompanying drawings. These drawings are a part of the disclosure of the present invention, which are mainly used to illustrate the embodiments, and can be combined with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these contents, those skilled in the art should understand other possible implementations and advantages of the present invention. Components in the figures are not drawn to scale, and similar component symbols are generally used to denote similar components.

[0093] The term "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 area near the optical axis. "The object side (or image side) of a lens includes a convex surface (or concave surface) in a certain area" means that...

Abstract

The invention is related to a portable electronic device and its optical imaging lens. The present invention provides an optical imaging lens, which sequentially includes a first, second, third, fourth, fifth, and sixth lenses from the object side to the image side, and the optical imaging lens only includes the above six lenses with diopter High-efficiency lenses, and satisfy the following conditions: 1.4≦G23 / G56, TTL / T4≦19.0, and 0.96≦T3 / T4. The present invention also provides a portable electronic device, comprising: a casing; and an image module installed in the casing, the image module includes the above-mentioned optical imaging lens, a lens barrel, a module rear seat unit and An image sensor. The present invention controls the concavo-convex surface arrangement of each lens and controls related parameters with a conditional formula, thereby shortening the length of the lens under the condition of maintaining good optical performance. The present invention is used for imaging.

Description

technical field [0001] The present invention is related to a portable electronic device and its optical imaging lens, and especially related to a portable electronic device using a six-piece lens and its optical imaging lens. Background technique [0002] In recent years, the popularization of mobile phones and digital cameras has led to the vigorous development of photographic modules including optical imaging lenses, lens barrels, and image sensors. The thinner and lighter mobile phones and digital cameras have also increased the demand for miniaturization of photographic modules. With the technological progress and size reduction of Charge Coupled Device (CCD) or Complementary Metal-Oxide Semiconductor (CMOS), the optical imaging lens installed in the camera module also needs to be reduced in size. But the good optical performance of the optical imaging lens is also necessary to take into account. [0003] With consumers' demand for imaging quality, the traditional four-...
