Abstract

The invention discloses a filter. The optical filter includes a first lens and a second lens which are arranged oppositely at intervals. The two opposite surfaces of the first mirror and the second mirror are provided with high reflective film layers. The first lens and the second lens can move relatively to change the size of the gap between the first lens and the second lens, so that the filter can switch between the visible light mode and the infrared light mode. When in visible light mode, the filter only lets through visible light; when in infrared light mode, the filter only lets through infrared light. The invention also discloses a lens module and an imaging module. The optical filter, the lens module and the imaging module of the embodiment of the present invention use two mirrors arranged in parallel at intervals as the optical filter. By changing the gap between the two mirrors, the optical filter can pass infrared light and Visible light, so that only one camera can realize the functions of visible light shooting and infrared light shooting.

Description

technical field [0001] The invention relates to the field of imaging technology, in particular to an optical filter, a lens module and an imaging module. Background technique [0002] When the iris recognition technology is applied on a mobile device, since the iris recognition needs to work in the infrared band, an infrared camera needs to be specially installed on the mobile device to realize the iris recognition function. But this not only increases the hardware cost, but also reduces the available space of the screen of the mobile device. Contents of the invention [0003] Embodiments of the invention provide an optical filter, a lens module and an imaging module. [0004] The optical filter according to the embodiment of the present invention includes a first lens and a second lens arranged oppositely at intervals, and high reflective film layers are arranged on the opposite surfaces of the first lens and the second lens, and the first The lens and the second lens c...
