Abstract

An optical imaging system is provided. The optical image capturing system includes a first lens, a second lens, a third lens, a fourth lens, and a fifth lens disposed in order from an object side to an image side. The first lens has positive refractive power, and the second lens has negative refractive power. TTLgt; the first lens has a length of 10.2 mm, and TTL / (2 * IMG HT) < = 1.7, where TTL is a distance on the optical axis from the object-side surface to the imaging surface of the first lens, and IMG HT is equal to half a diagonal length of the imaging surface.

Description

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS [0002] This application claims the benefit of priority from Korean Patent Application No. 10-2021-0132520 filed in the Korean Intellectual Property Office on October 6, 2021, the entire disclosure of which is incorporated herein by reference for all Purpose. technical field [0003] The following description refers to optical imaging systems. Background technique [0004] The portable terminal may include a camera including an optical imaging system combined with a plurality of lenses to perform operations such as, but not limited to, video calling and image capture. [0005] As operations performed by cameras included in portable terminals gradually increase, the demand for high-resolution cameras for portable terminals increases. [0006] Image sensors with high pixel counts (eg, 13 to 100 million pixels, etc.) can be used for incorporation into cameras in portable terminals to achieve improved image quality. [0007] In ...
