But the dust pollution that optical filter can be all generated during production, transport and assembling etc., make dirt pits problem
It is the insoluble a great problem of those skilled in the art.
Utility model content
To solve the above problems, the utility model provides a kind of optical filter, by increasing plating two again on the surface of optical filter
Layer hydrophobic layer, to reduce the extraneous dirty adhesive force on optical filter surface, so that optical filter surface more cleans.
To achieve the above object, the utility model provides following technical solution：
A kind of optical filter, the optical filter include：
Substrate；
It is arranged on the antireflective coating of the substrate side；
The substrate is arranged on away from the infrared by film layer of the antireflective coating side；
It is arranged on the first hydrophobic layer that the antireflective coating deviates from the substrate side；
It is arranged on infrared second hydrophobic layer for deviating from the substrate side by film layer.
Preferably, in above-mentioned optical filter, the substrate is glass substrate.
Preferably, in above-mentioned optical filter, the water droplet angle of the optical filter meets preset range.
Preferably, in above-mentioned optical filter, the thickness range of first hydrophobic layer is 200nm-2000nm, including endpoint
Value.
Preferably, in above-mentioned optical filter, the thickness range of second hydrophobic layer is 200nm-2000nm, including endpoint
Value.
The utility model additionally provides a kind of camera module, and the camera module includes the filter described in any of the above-described
Mating plate.
The utility model additionally provides a kind of electronic equipment, and the electronic equipment includes camera module described above.
By foregoing description, a kind of optical filter provided by the utility model includes：Substrate；It is arranged on the substrate one
The antireflective coating of side；The substrate is arranged on away from the infrared by film layer of the antireflective coating side；It is arranged on described anti-reflection
Film layer deviates from the first hydrophobic layer of the substrate side；Be arranged on it is described it is infrared by film layer deviate from the substrate side second
Hydrophobic layer.
That is, by increasing two layers of hydrophobic layer of plating again on the surface of optical filter, it is extraneous dirty in optical filter table to reduce
The adhesive force in face, so that optical filter surface more cleans.
Brief description of the drawings
In order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment
