Embodiment Construction
[0113] 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.
[0114] The term "a lens has positive refractive power (or negative refractive power)" mentioned 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" ...

The invention provides a portable electronic device and its optical imaging lens. The invention discloses an optical imaging lens which sequentially includes a diaphragm, a first, second, third, fourth, fifth and sixth lenses from the object side to the image side, and satisfies the condition of T4 / G45≦2.8 Formula, T4 is the thickness of the fourth lens on the optical axis, G45 is the width of the air gap between the fourth lens and the fifth lens on the optical axis. The present invention also discloses 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 invention is used for photography, and shortens the lens length under the condition of maintaining good optical performance by controlling the concave-convex curved surface arrangement of each lens.
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-...
