Abstract

An imaging lens system includes a first lens, a second lens, a third lens, a fourth lens, a fifth lens, a sixth lens, and a seventh lens sequentially disposed at intervals from an object side of the imaging lens system. The imaging lens system satisfies 1.5<Nd5<1.6, 30<V5<50, and TTL / 2IH<0.730, where Nd5 is the refractive index of the fifth lens, V5 is the Abbe number of the fifth lens,TTL is thedistance from the object-side surface of the first lens to the imaging surface, and 2IH is the diagonal length of the imaging surface.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of priority to Korean Patent Application No. 10-2019-0071406 filed with the Korean Intellectual Property Office on June 17, 2019, the entire disclosure of which is hereby incorporated by reference for all purposes Application. technical field [0003] The following description refers to an imaging lens system including seven lenses. Background technique [0004] Compact cameras can be mounted on wireless terminals. For example, compact cameras may be mounted on the front and rear surfaces of the wireless terminal, respectively. Such compact cameras are used for various purposes, such as outdoor landscape photography, indoor portrait photography, etc., requiring performance not inferior to ordinary cameras. However, it is difficult to achieve high performance since compact cameras are limited by installation space due to the size of wireless terminals. Therefore, it is necessary t...
