Abstract

There is provided an optical system including: a first lens having positive refractive power; a second lens having positive refractive power; a third lens having refractive power and having a convex object-side surface; a fourth lens having refractive power; and a fifth lens having refractive power, wherein the first to fifth lenses are sequentially disposed from an object side, whereby spherical aberration and coma aberration may be improved to realize high resolution in images captured thereby and increase an amount of light incident through the lenses to an image sensor.

Description

[0001] This application claims priority and benefit from Korean Patent Application No. 10-2014-0130796 filed with the Korean Intellectual Property Office on September 30, 2014, the disclosure of which is hereby incorporated by reference. technical field [0002] The present disclosure relates to an optical system. Background technique [0003] Recently, mobile communication terminals have been commonly provided with camera modules to enable image capture and video calls. Furthermore, as the level of functions of cameras in such mobile communication terminals has gradually increased, cameras used in mobile communication terminals are increasingly required to have higher levels of resolution and performance. [0004] However, since mobile communication terminals tend to be miniaturized and lightweight, there are limitations in obtaining a camera module having a high level of resolution and a high level of performance. [0005] To solve these problems, recently, camera lenses ...
