anidolic

adj

1. (not-comparable)Pertaining to nonimaging transfer of light, particularly in the domain of indoor natural lighting.

   “Zenithal openings (Couret et al. 1994) are also attracting interest because they provide a high illuminance level; an anidolic toplighting consists of a compound parabolic concentrator which concentrates light in its top mirror and then diffuses it with its bottom one (Figure 3.21). It protects against direct sunlight, something difficult with atria.”

   “An anidolic reflector offers the prospect of being able to concentrate diffuse light from a selected portion of the sky, and transmit that light to another anidolic reflector where it will be 'deconcentrated' and diffused within an interior space.”
