Title:
OPTICAL IMAGING SYSTEM AND ELECTRONIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/003721
Kind Code:
A1
Abstract:
An optical imaging system and an electronic device. The optical imaging system (100) sequentially comprises, from an object side to an image side, a first lens (101) having a negative refractive power, the surface of the object side being a convex surface, and the surface of the image side being a concave surface; a second lens (102) having a positive refractive power, the surface of the object side being a convex surface; a third lens (103) having a negative refractive power, the surface of the object side being a concave surface, and the surface of the image side being a concave surface; a fourth lens (104) having a positive refractive power, the surface of the object side being a convex surface, and the surface of the image side being a convex surface; a fifth lens (105) having a positive refractive power, the surface of the object side being a concave surface, and the surface of the image side being a convex surface; and a sixth lens (106) having a negative refractive power, the surface of the image side being a concave surface. The optical imaging system and the electronic device have a high degree of miniaturization, a light overall weight and a good imaging effect, and are also beneficial to correcting the problem of temperature drift.
