Abstract

The present disclosure provides an optical imaging system. The optical imaging system includes: a first lens and a second lens that are sequentially arranged from the object direction of the optical imaging system toward the imaging surface of the optical imaging system and each have a refractive power. , the third lens, the fourth lens, the fifth lens and the sixth lens, wherein the full field angle of the optical imaging system is 50° or greater, and TTL / f<1.0, wherein the TTL is obtained from the The distance from the object-side surface of the first lens to the imaging surface, and f is the total focal length of the optical imaging system.

Description

[0001] This application claims priority and benefit from Korean Patent Application No. 10-2018-0016407 filed with the Korean Intellectual Property Office on February 9, 2018, the entire disclosure of which is incorporated by reference for all purposes at this. technical field [0002] The present application relates to a telescopic optical imaging system including six lenses. Background technique [0003] A small camera module is installed in a mobile communication terminal. For example, a small camera module can be installed in a thin device such as a mobile phone. Such a compact camera module includes an optical imaging system including a small number of lenses so that it can be made thin. For example, the optical imaging system of a small camera module includes four or fewer lenses. However, it is difficult to realize telephoto characteristics and high-resolution characteristics in such an optical imaging system including only four lenses or less. Contents of the inv...
