OPTICAL IMAGING LENS ASSEMBLY

摘要

This disclosure discloses an optical imaging lens assembly, sequentially arranged from an object side to an image side along an optical axis, comprising: the first lens element with positive refractive power, the second lens element with negative refractive power having a convex object-side surface and a concave image-side surface, the third lens element with positive refractive power, the fourth lens element with negative refractive power having a concave object-side surface and a convex image-side surface, the fifth lens element with refractive power having a concave image-side surface, and both object-side surface and image-side surface being aspheric, wherein a stop and an image sensor disposed on an image plane are also provided. By such arrangements, the image pickup optical system satisfies conditions related to shorten the total length and to reduce the sensitivity for use in compact cameras and mobile phones with camera functionalities.
