Abstract

The invention discloses an optical imaging lens assembly. The optical imaging lens assembly includes, in order from an object side to an image side: a first lens element, a second lens element, a third lens element, a fourth lens element, a fifth lens element and a sixth lens element. The second lens element has positive refractive power. The third lens element has negative refractive power. The fifth lens element has positive refractive power. The sixth lens element has negative refractive power. At least one surface among object-side surfaces and image-side surfaces of the six lens elementsof the optical imaging lens assembly has at least one critical point in an off-axial region thereof and is aspheric.

Description

technical field [0001] The present invention relates to an optical image capturing mirror group, an image capturing device and an electronic device, in particular to an optical image capturing mirror group and an image capturing device suitable for an electronic device. Background technique [0002] In recent years, with the vigorous development of miniaturized photographic lenses, the demand for miniature photographic modules has increased day by day, and with the advancement of semiconductor technology, the pixel size of photosensitive elements has been reduced. The appearance of the development trend. Therefore, miniaturized photographic lenses with good imaging quality have become the mainstream in the current market. [0003] As the application of camera modules becomes more and more extensive, it will be a major trend of future technological development to install camera modules in various intelligent electronic products, vehicle devices, identification systems, enter...
