Abstract
The invention is an optical lens assembly for capturing images and an image capture device therewith. The optical lens assembly for capturing images includes, along an optical axis, a total reflection prism, a first lens group having negative focal power, wherein the first lens group comprises a lens having negative focal power, a second lens group having positive focal power, wherein the second lens group comprises at least one lens having an aspherical optical surface, a third lens group having positive focal power, wherein the third lens group comprises at least one lens having positive focal power and at least one lens having negative focal power, and a fourth lens group having positive focal power, wherein the fourth lens group comprises at least one lens having an aspherical optical surface. Thereby, the aberration can be improved and a thin lens module for capturing images can be achieved.
