Title:
PERISCOPIC PHOTOGRAPHING MODULE
Document Type and Number:
WIPO Patent Application WO/2022/037320
Kind Code:
A1
Abstract:
Provided is a periscopic photographing module, which comprises: an optical path turning element; a wafer-grade lens, which is provided at a transmitting end of the optical path turning element, the wafer-grade lens being produced by cutting a lens wafer, where the lens wafer is a combination produced by stacking together multiple lens wafer sets, each of the lens wafers comprises a lens array consisting of multiple lens units, at least one surface with which each of the lens units is provided is a light-transmitting curved surface, and the contour of the light-transmitting curved surface is circular; and a photosensitive component, which is used for receiving an optical signal passing through the wafer-grade lens and outputting imaging data. The present application avoids the problem of inconsistent surface shape precision in two directions perpendicular to each other caused by a D-cut lens forming process, thus ensuring imaging quality. Inconsistent surface shape precision causes problems such as astigmatism and is difficult to compensate by means of a subsequent module assembly process.
