Abstract: A concentrator including a volume of at least partially transmissive material and a plurality of facets disposed at at least one surface thereof. Each of the facets is disposed at a position dependent angle relative to the surface effective to cause an internal reflection of energy applied to the layer whereby the density of the applied energy varies as a function of position. In the illustrative implementation, the volume is an active medium, i.e., a slab. The slab has substantially parallel, planar upper and lower surfaces and first and second edges therebetween. A plurality of cladding layers are disposed on the upper and lower surfaces of the slab. The facets are provided in the cladding layers on the upper and lower surfaces of the slab and angled as a function of distance relative to the first or the second edge. The facets provide a Fresnel reflecting surface or a binary optic surface.

Abstract: A radiance source (20) includes a housing (40) having an interior wall (42), wherein at least a spherical portion of the interior wall (42) of the housing (40) is spherical, an interior volume (46) and an exit port (48). A light source (82) is disposed within the interior volume (46) of the housing (40). A calibration structure (84) blocks and reflects a light ray that would otherwise travel directly from the light source (82) to the exit port (48) without reflecting from the interior wall (42). The calibration structure (84) has a calibration body (86) having a curved back surface (88) facing the light source (82) and a curved front surface (90) facing the exit port (48). There is an optically diffuse, lambertian reflecting surface (96) on at least the spherical portion of the interior wall (42) of the housing (40), the back surface (88) of the calibration body (86), and the front surface (90) of the calibration body (86).
