Title
(EN) IMAGE CAPTURING OPTICAL LENS
(JA) 撮像光学レンズ
Abstract
(EN)

PROBLEM TO BE SOLVED: To provide an optical lens, in particular an image capturing optical lens.

SOLUTION: An image capturing optical lens provided herein comprises, in order from the object side to the image side, a first lens, a second lens, a third lens, a fourth lens, a fifth lens, and a sixth lens, where the second lens has positive refractive power and the third lens has positive refractive power. The image capturing optical lens satisfies the following conditional expressions: 1.40≤f1/f3≤5.00, 2.50≤R5/R6≤6.00. The image capturing optical lens offers high imaging performance and a short total track length (TTL).
