Title:
OPTICAL LENS, IMAGE CAPTURING MODULE, ELECTRONIC DEVICE, AND DRIVING DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/016316
Kind Code:
A1
Abstract:
An optical lens (100), an image capturing module (200), an electronic device, and a driving device (300). The optical lens (100) sequentially comprises, from an object side to an image side along an optical axis: a first lens (L1) having negative refractive power, an object side surface (S1) thereof being a convex surface at a paraxial region, and an image side surface (S2) being a concave surface at a paraxial region; a second lens (L2) having negative refractive power, an image side surface (S4) thereof being a concave surface at a paraxial region; a third lens (L3) having positive refractive power; a fourth lens (L4) having negative refractive power; a fifth lens (L5) having positive refractive power, an object side surface (S9) thereof being a convex surface at a paraxial region; and a sixth lens (L6) having negative refractive power, an image side surface (S12) being a convex surface at a paraxial region. The sixth lens (L6) and the fifth lens (L5) are cemented. The optical lens (100) further comprises a diaphragm (ST0), the diaphragm (ST0) is provided at the object side (S1) of the first lens (L1) or between the first lens (L1) and the sixth lens (L6), and the object side surface and/or the image side surface of at least one lens of the first lens (L1) to the sixth lens (L6) is aspherical. When a specific relationship is satisfied, the effects of expanding a viewing angle range, ensuring high imaging performance, and implementing miniaturization can be simultaneously realized.
