Abstract
The invention relates to an interference filter () for receiving an incident light () and selecting a light component of the incident light to be transmitted (). The interference filter () includes a metal mirror (), a dielectric mirror (), and a spacer () placed between the metal mirror () and the dielectric mirror (). The metal mirror () and the dielectric mirror () are configured to enable optical interference in the spacer () to select the light component of the incident light to be transmitted (). Using one metal mirror and one dielectric mirror allows achieving a spectral response with high finesse and large rejection band while reducing the total number of layers in the filter and reducing the number of additional filters necessary for removing transmitted side bands, relative to prior art approaches.
