Abstract

A photographing optical lens system 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 first lens element has negative refractive power. The second lens element has an image-side surface being convex in a paraxial region thereof. The third lens element has positive refractive power. The fourth lens element has negative refractive power. The sixth lens element with negative refractive power has an object-side surface being concave in a paraxial region thereof and an image-side surface being planar or convex in a paraxial region thereof.

Description

technical field [0001] The present invention relates to an image pickup optical system mirror group and an image pickup device, and in particular to a miniaturized image pickup optical system mirror group and an image pickup device applied to an electronic device. Background technique [0002] As the application of camera modules becomes more and more diverse, the specification requirements for camera modules are becoming more and more stringent, and the current market demand for miniaturization and imaging quality is also increasing. In addition, in order to expand the camera range, the field of view angle of the camera module continues to increase. However, the traditional wide-angle lens is limited in terms of mirror shape and lens material, which makes it difficult to reduce the size of the wide-angle lens, thus limiting the scope of application. Therefore, the current market is still looking for a lens that can take into account wide viewing angle, miniaturization and ...
