Embodiment Construction

[0127] The present disclosure provides an imaging optical lens system including four lenses, the four lenses are a first lens, a second lens, a third lens and a fourth lens in sequence from the object side to the image side of the optical path.

[0128] The first lens may have a positive refractive power, which is helpful for reducing the total length of the imaging optical lens system and meeting the requirement of miniaturization. The object-side surface of the first lens can be convex near the optical axis, which can strengthen the refractive power of the first lens.

[0129] The second lens may have a negative refractive power, which may balance the aberrations created by compressing the volume of the imaging optical lens system. The image-side surface of the second lens may be concave near the optical axis, which helps to correct aberrations such as astigmatism.

[0130] The third lens can have a positive refractive power, which can disperse the positive refractive power...

Abstract

A camera shooting optical lens system, an image capturing device and an electronic device, the camera shooting optical lens system includes four lenses, the four lenses are a first lens, a second lens, a third lens and a fourth lens in order from an object side to an image side of an optical path. The first lens element has an object-side surface being convex in a paraxial region thereof. The third lens element with positive refractive power has an object-side surface being convex in a paraxial region thereof and an image-side surface being concave in a paraxial region thereof. The fourth lens element has negative refractive power. When specific conditions are satisfied, the manufacturing difficulty or ghosting generation can be reduced.

Description

technical field [0001] The present disclosure relates to an imaging optical lens system and an imaging device, and more particularly, to a miniaturized imaging optical lens system and an imaging device applied to an electronic device. Background technique [0002] With the improvement of semiconductor process technology, the performance of electronic photosensitive elements has been improved, and the pixel size can be smaller. Therefore, optical lenses with high imaging quality have become an indispensable part. With the rapid development of science and technology, the application range of electronic devices equipped with optical lenses is more extensive, and the requirements for optical lenses are also more diverse, because the optical lenses in the past are not easy to meet the requirements of imaging quality, sensitivity, aperture size, volume or angle of view. Therefore, the present invention provides an imaging optical lens system to meet the requirements. SUMMARY OF ...
