摘要:
An optical lens assembly with a filter member for image taking, sequentially arranged from an object side to an image side along an optical axis, comprises: a filter member and a lens assembly. The lens assembly is set at the object side of the filter member. The lens assembly comprises at least three lens elements with refractive powers, wherein at least two lens elements are made of plastic, and have at least one aspheric object-side surface or image-side surface. By such arrangements, the optical lens assembly with a filter member for image taking can have good chromatic aberration correction and reduce the total length for applications to electronic products such as cameras and mobile phones requiring high resolution.
