Abstract

Apodized filters and mirrors based on the frustrated-internal-reflection effect have been proposed and developed^1,2. These elements consist of two glass prisms almost in contact along one of their surfaces, which, instead of being planar, are optically polished at a suitable curvature. When the light impinges upon the interface at an angle at which total internal reflection occurs, the light is transmitted with a transversely varying transmission profile.
