    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.

    Doctorate students at our University can find in the Syllabus a course entitled Dialogues on Anidolic Optics. The inquiring reader might ask what anidodlic means. It is nothing but non-imaging in Greek, but (to us) it sounds better. As researchers in this field we cannot allow ourselves to deal with common names as charm or others used by the particle physicist, as we deal with a venerable and traditional science (old fashioned even, as perhaps we at this Institute are): geometrical optics, whose variational principles were already known by Plotine and other Ancient Greeks.

    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.
