Title:
OPTICAL LENS SYSTEM, IMAGE CAPTURING DEVICE AND ELECTRONIC APPARATUS
Document Type and Number:
WIPO Patent Application WO/2024/078202
Kind Code:
A1
Abstract:
Provided in the present application are an optical lens system, an image capturing device and an electronic apparatus. The optical lens system provided in the present application sequentially comprises, from an object side to an image side: a prism having total reflection, a first lens having a positive refractive power, a second lens having a negative refractive power, a third lens having a positive refractive power, a fourth lens having a positive refractive power, and a fifth lens having a negative refractive power, wherein object-side surfaces and image-side surfaces of the first lens, the second lens, the third lens, the fourth lens and the fifth lens are all non-spherical surfaces. The optical lens system satisfies the following conditional expression: TTL/EFL < 1.05, where TTL is the total track length of the optical lens system, and EFL is the effective focal length of the optical lens system. A periscope telephoto lens is formed by the optical lens system of the present application, same can meet photographing requirements of a telephoto lens having a large image surface, and has a good imaging effect while ensuring miniaturization and ultra-thinness, thereby improving the imaging quality.
