Problems solved by technology

[0002] The variable optical filter device may include two mirrors parallel to each other. Generally, multiple drivers drive the lenses to move to change the distance between the lenses, and are used to adjust the wavelength of the outgoing light of the variable optical filter device. However, due to different driving The difference in the accuracy of the components may cause the lenses to be non-parallel, resulting in poor filtering effect of the variable filter device

Abstract

The invention discloses a filter. The filter comprises a first lens, a second lens, a parallel detection assembly and a drive assembly. The first lens and the second lens are arranged oppositely at interval, and a high reflection film layer is arranged on each of the two opposite surfaces of the first lens and the second lens. The parallel detection assembly is used for detecting whether the two high reflection film layers are parallel. The drive assembly is used for driving the first lens or the second lens to move when the high reflection film layers are not parallel, so that the two high reflection film layers are parallel. The invention further discloses a lens module and an imaging module. The filter, the lens module and the imaging module have the advantages that when the parallel detection assembly detects that the two high reflection film layers are not parallel, the drive assembly can drive the first lens or the second lens to move, so that the two high reflection film layersare parallel to ensure a good filtering effect of the filter.

Description

technical field [0001] The invention relates to the field of imaging technology, and more specifically, to an optical filter, a lens module and an imaging module. Background technique [0002] The variable filter device can include two mirrors parallel to each other. Generally, multiple drivers drive the lenses to move to change the distance between the lenses, and are used to adjust the wavelength of the outgoing light of the variable filter device. However, due to different driving Differences in the accuracy of the components may cause the lenses to be non-parallel, resulting in poor filtering effect of the variable filter device. Contents of the invention [0003] The embodiments of the present invention provide an optical filter, a lens module and an imaging module. [0004] The optical filter of the embodiment of the present invention comprises: [0005] A first lens and a second lens arranged oppositely at intervals, and high reflective film layers are arranged on...
