Silk screen optical filter

The invention discloses a silk screen optical filter which comprises first protective glass, second protective glass and a silk screen arranged between the first protective glass and the second protective glass. The silk screen is a metal wire mesh etched on a TAC substrate, and the surface of the metal wire mesh is sequentially plated with a copper layer and a nickel layer. By means of the silk screen optical filter, the transmittance of the silk screen can be improved by 10%, the reflection coefficient of a displayer module mirror surface is reduced to 0.7%, and the diffuse reflection coefficient is reduced to 0.5%. The silk screen optical filter is good in transmittance, high in optical energy utilization rate, good in use safety and strong in shielding performance.
