Polarization filter, camera and intelligent equipment

Abstract

The utility model discloses a polarization filter, a camera and intelligent equipment, and the polarization filter is characterized in that the polarization filter comprises a base material which is a transparent material; the wire grating is positioned on one side of the base material and is used for enabling light rays in a specific vibration direction to pass through; the coating film is positioned on the other side of the base material and is used for enabling light rays with specific spectrums to pass through; the wire grating and the coating film are positioned on opposite sides of the base material and are in direct contact with the base material. According to the utility model, the integration of polarization and filtering functions is realized, the thickness is reduced, the number of devices and assembly procedures are reduced, and good product structure design matching performance and cost economy are achieved.
