Abstract
The interference filter structure has a filter with a top side and a bottom side, a partially reflecting/transmitting thin metal layer, dielectric spacers on each sides of the partially transparent layer and a semi-absorbing film on at least a portion of top side or bottom side of the dielectric spacers. The filter provides a reflection mode when observed from the top or bottom side and light transmission is side independent.
