WIPO Patent Application WO/2021/184167
Kind Code:
A1
Abstract:
A lens system (10), an imaging module (20) and an electronic device. The lens system (10) comprises: a plurality of optical elements arranged along a folding optical axis thereof, comprising, in order from an object side to an image side: a first optical path folding element (P1), located on a first portion (AX1) of the folding optical axis and used for directing light from the first portion (AX1) of the folding optical axis to a second portion (AX2) of the folding optical axis; a lens group, located on the second portion (AX2) of the folded optical axis; a second optical path folding element (P2), used to direct light from the second portion (AX2) of the folding optical axis to a third portion (AX3) of the folding optical axis; a third optical path folding element (P3), used to direct light from the third portion (AX3) of the folding optical axis to a fourth portion (AX4) of the folding optical axis; and the second portion (AX2), the third portion (AX3) and the fourth portion (AX4) of the folding optical axis are located in the same plane, and the plane is perpendicular to the first portion (AX1) of the folding optical axis. The lens system (10) may be transversely arranged along a housing of an electronic product while realizing long focal length, so that the space of the electronic product is fully utilized, and so that the design requirements for the electronic product to be light and thin are met.
