Embodiment Construction

[0131] The present invention will now be further described with reference to the drawings and specific embodiments.

[0132] Before the present invention is described in detail, it should be noted that in the following description, similar components are represented by the same numbers.

[0133] In this specification, "a lens has a positive refractive power (or a negative refractive power)" refers to the positive (or negative) refractive power on the optical axis of the lens calculated by Gaussian optics theory. The image side and object side are defined as the range through which the imaging light passes. The imaging light includes chief ray Lc and marginal ray Lm, such as figure 1 As shown, I is the optical axis and this lens is radially symmetrical with the optical axis I as the symmetry axis. The area where light passes through the optical axis is the area near the optical axis A, and the area where the edge light passes is the area near the circumference C. In addition, the le...

Abstract

The invention relates to an optical imaging lens and an electronic device applying the optical imaging lens. The optical imaging lens comprises six lenses and is characterized in that an object side surface of the second lens is provided with a convex surface portion located in an area nearby an optical axis and a concave surface portion located in an area nearby the circumference; an image side surface of the third lens is provided with a convex surface portion located in an area nearby the optical axis and a concave surface portion located in an area nearby the circumference; an object side surface of the fourth lens is provided with a concave surface portion located in an area nearby the optical axis; an object side surface of the fifth lens is provided with a convex surface portion located in an area nearby the optical axis; and the ratio of the total sum of thicknesses of the six lenses on the optical axis I ALT to an air gap G23 between the second lens and the third lens on the optical axis meets the formula that ALT / G23 is less than or equal to 21.00. The electronic device provided by the invention comprises a casing and an image module, wherein the image module is installed in the casing and comprises the optical imaging lens, a lens cone, a module rear base unit and an image sensor. The optical imaging lens and the electronic device applying the optical imaging lens can provide excellent 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 rapid development of image module related technologies. The image module mainly includes components such as optical imaging lenses, module holder units, and sensors. The trend toward thinner and lighter digital cameras has also increased the demand for miniaturization of image modules. With the development of Charge Coupled Device (CCD) or Complementary Metal-Oxide Semiconductor (Complementary Metal-Oxide Semiconductor) Due to the technological advancement and size reduction of CMOS), the optical imaging lens mounted in the image module also needs to be shortened correspondingly. However, in order to avoid the degradation of photographic effects and quality, the optic...
