Abstract

The invention discloses an optical pick-up lens group, an image capture module and an electronic device. An optical camera lens group sequentially comprises a diaphragm, a first lens with positive refractive power, a second lens, a third lens, a fourth lens, a fifth lens with positive refractive power and a sixth lens with negative refractive power from an object side to an image side. The image side surface of the first lens is a concave surface at the optical axis; the object side surface of the second lens is a convex surface at the optical axis; the object side surface of the third lens isa convex surface at the optical axis; at least one inflection point is arranged on the object side surface of the fifth lens; the image side surface of the sixth lens is a concave surface at the optical axis, and at least one of the object side surface and the image side surface of the sixth lens is provided with at least one inflection point; wherein f is the focal length of the optical pick-uplens group, and CT5 is the center thickness of the fifth lens on the optical axis, and the optical pick-up lens group, the image capture module and the electronic device can guarantee miniaturizationof an optical imaging system while obtaining excellent imaging quality.

Description

technical field [0001] The invention relates to optical imaging technology, in particular to an optical camera lens group, an imaging module and an electronic device. Background technique [0002] At present, although the four-element or five-element optical camera lens group can meet the miniaturization requirements, the unbalanced configuration of the lens refractive power may easily cause excessive off-axis aberrations that are difficult to correct, making the electronic photosensitive element receive the light emitted by the object. Poor efficiency affects image quality. Contents of the invention [0003] To solve the technical problem that the four-piece or five-piece optical camera lens group in the prior art cannot simultaneously meet the requirements of optical overall length and imaging quality, the embodiment of the present invention provides an optical camera lens group, an imaging module and an electronic device. [0004] The optical camera lens group accordin...
