Beschreibung
Zusammenfassung:	According to the invention, the extractor is a concentrator by reflection, the input section of the extractor (311) has a surface area that is greater than that of its output section (313), the reflective lateral walls (312) of the extractor (31) have an adapted shape so that an outage angle Rlim exists that corresponds to a limit wavelength UC.lim of transmission of this extractor for a given optical cavity. The invention is for use in diode panels for visualizing images. The invention provides a widening of angles of view and an improvement in the purity of colors and visualized images.
