Abstract

The invention relates to a lens system, an imaging module and an electronic device. The lens system includes a plurality of optical elements arranged along a folding optical axis thereof, including, in order from an object side to an image side, a first optical path folding element on a first portion of the folding optical axis for directing light from the first portion of the folding optical axisto a second portion of the folding optical axis; a lens group on the second portion of the folded optical axis; a second optical path folding element to direct light from a second portion of the folding optical axis to a third portion of the folding optical axis; a third optical path folding element to direct light from a third portion of the folding optical axis to a fourth portion of the folding optical axis; the second part, the third part and the fourth part of the folding optical axis are located in the same plane, and the plane is perpendicular to the first part of the folding optical axis. The lens system can be transversely arranged along the shell of the electronic product while realizing long focal length, so that the space of the electronic product is fully utilized, and the light and thin design requirements of the electronic product are met.

Description

technical field [0001] The invention relates to the technical field of optical imaging, in particular to a lens system, an imaging module and an electronic device. Background technique [0002] In recent years, with the development of science and technology, more and more periscope mobile phone lenses have been applied to portable electronic products. The periscope mobile phone lens has a prism part that can change the direction of the optical path, and when installed, the lens can be placed horizontally in the housing of the electronic product, thereby reducing the lateral length and overall height of the lens, thereby realizing the thinning and lightening of the mobile phone. [0003] However, under the development trend of thinner and lighter electronic products, it is still difficult for traditional periscope lenses to achieve long focal lengths or ultra-long focal lengths. Contents of the invention [0004] Based on this, it is necessary to provide an improved lens s...
