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 an optical filter. The optical filter comprises a first lens, a second lens, a parallel detection assembly and an actuator. The first lens and the second lens are oppositely arranged in a separated mode, and the two opposite surfaces of the first lens and the second lens are both provided with highly reflective coating layers. The parallel detection assembly is used for detecting whether or not the two highly reflective coating layers are parallel. The actuator is used for driving the first lens to move oppositely to the second lens to change the size of the gap between the first lens and the second lens, and further used for driving the first lens or the second lens to move in order to make the two highly reflective coating layers parallel to each other when the highly reflective coating layers are not parallel. The invention further discloses a lens module and an imaging module. According to the optical filter, the camera lens module and the imaging module, when the parallel detection assembly detects that the two highly reflective coating layers are not parallel, the actuator can drive the first lens or the second lens to move to make the two highly-reflective coating layers parallel and ensure that the optical filter can have a great optical filtering effect.

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...
