Title:
OPTICAL IMAGING SYSTEM, IMAGE CAPTURE MODULE, ELECTRONIC APPARATUS, AND AUTOMOBILE
Document Type and Number:
WIPO Patent Application WO/2022/040938
Kind Code:
A1
Abstract:
An optical imaging system (10), which sequentially comprises, from an object side to an image side: a first lens (L1) having a negative refractive power; a second lens (L2) having a negative refractive power; a third lens (L3) having a positive refractive power; a fourth lens (L4) having a positive refractive power; a fifth lens (L5) having a positive refractive power; and a sixth lens (L6) having a negative refractive power. The optical imaging system (10) satisfies the following conditional expression: 1/(ni486 - ni950) ≤ 30, wherein 1/(ni486 - ni950) is the difference between the refractive index of an ith lens under reference light of 486 nm and the refractive index of the ith lens under reference light of 950 nm. The optical imaging system (10) has relatively good imaging capability in environments with different light brightnesses. Further provided are an image capture module (100) having the optical imaging system (10), and an electronic apparatus (200) and an automobile (300) having the image capture module (100).
