lens module

Abstract

The present invention provides a lens module. The lens module includes: a first lens with positive refractive power; a second lens with positive refractive power; a third lens with negative refractive power; a fourth lens with positive refractive power; Has positive or negative refractive power; the sixth lens has negative refractive power. One or more inflection points may be formed on an image-side surface of the sixth lens.

Description

[0001] This application claims Korean Patent Application No. 10-2014-0073657 filed with the Korean Intellectual Property Office on June 17, 2014 and Korean Patent Application No. 10-2014-0137760 filed with the Korean Intellectual Property Office on October 13, 2014 Priority and benefit of patent application, the disclosures of said two Korean patent applications are hereby incorporated by reference in their entirety. technical field [0002] Some embodiments of the present disclosure may relate to a lens module having an optical system including six or more lenses. Background technique [0003] A lens module installed in a camera device provided in a portable terminal generally includes a plurality of lenses. For example, such a lens module may include six lenses to provide an optical system with high resolution. [0004] However, in the case of configuring such an optical system with high resolution using a plurality of lenses as described above, the length of the optical ...

Problems solved by technology

[0004] However, in the case of constructing such an optical system with high resolution using a plurality of lenses as described above, the length of the optical system (the distance from the object side surface of the first lens to the image sensing surface) may increase

In this case, it may be difficult to mount the lens module in relatively thin devices or portable terminals
