Induced transmission filter comprising a plurality of dielectric layers and a plurality of metal layers associated with a drop in peak transmission in a passband from approximately 78% at an angle of incidence of approximately 0 degrees to approximately 70% at an angle of incidence of approximately 50 degrees

An optical filter may include a first group of layers. The first group of layers may include alternating layers of a first dielectric material, of a group of dielectric materials, and a second dielectric material of the group of dielectric materials. The optical filter may include a second group of layers. The second group of layers may include alternating layers of a third dielectric material, of the group of dielectric materials, and a fourth dielectric material of the group of dielectric materials. The optical filter may include a third group of layers. The third group of layers may include alternating layers of a fifth dielectric material, of the group of dielectric materials, a sixth dielectric material, of the group of dielectric materials, and a metal material. The third group of layers may be disposed between the first group of layers and the second group of layers.
