Abstract

The optical image capturing system includes, in order from an object side, a first lens having a positive refractive power, a second lens having a negative refractive power and a refractive index higher than 1.6, a third lens having a refractive index higher than 1.6, a fourth lens having a positive refractive power, a sixth lens having a negative refractive power, an eighth lens having a refractive index higher than 1.6, and a ninth lens having a refractive index higher than 1.6. Any one of the third lens and the fourth lens has a refractive index higher than 1.6, the sixth lens has a negative refractive power and a refractive index higher than 1.6, and TTL / (2 * IMG HT) lt; tTL is the distance on the optical axis from the object side surface of the first lens to the imaging surface, and IMG HT is half the 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. 10-2020-0164581 filed in the Korean Intellectual Property Office on November 30, 2020, the entire disclosure of which is incorporated herein by reference for all purposes Application. technical field [0003] The present disclosure relates to optical imaging systems. Background technique [0004] Recently, mobile terminals are provided with a camera module including an optical imaging system having a plurality of lenses to realize video calling and image capture. [0005] In addition, as the functional level of the camera module in the mobile terminal is gradually increased, the camera module for the mobile terminal has been gradually required to have a higher resolution than the previous camera module. [0006] In addition, mobile terminals have been gradually miniaturized, and thus a camera module for the mobile terminal is required t...
