Abstract

An optical imaging system includes a first lens, a second lens, a third lens, a fourth lens, and a fifth lens sequentially disposed in ascending numerical order along an optical axis from an object-side surface of the first lens toward an imaging plane of the optical imaging system, wherein the conditional expression 11<=TTL / IMG_HT is satisfied, where TTL is a distance along the optical axis fromthe object-side surface of the first lens to the imaging plane, and IMG_HT is one-half of a diagonal length of the imaging plane.The invention further relates to a portable electronic device comprising three or more camera modules, and a first camera module in the camera modules comprises the optical imaging system.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of priority to Korean Patent Application No. 10-2019-0107669 filed with the Korean Intellectual Property Office on August 30, 2019, the entire disclosure of which is incorporated by reference into this application for all purposes . technical field [0003] The present application relates to optical imaging systems configured to fold optical paths. Background technique [0004] In an optical system in which a plurality of lenses are arranged along an optical axis, the overall length of the optical system generally increases as the number of lenses increases. For example, an optical imaging system including five lenses is more difficult to miniaturize than an optical imaging system including three lenses. For this reason, it may not be possible to mount a telephoto optical system with a long focal length in a thin portable electronic device. Contents of the invention [0005] The...
