Abstract
L'invention vise à proposer un élément optique à surface incurvée libre, une matrice de moulage et un dispositif optique, qui peuvent effectuer un positionnement extrêmement précis. Les côtés de miroir de première à troisième parties de maintien (27a - 27c), destinées à venir en butée contre une partie de maintien (18) pour ainsi positionner et fixer un miroir à surface incurvée libre (14), forment des première à troisième faces de référence de montage (29a - 29c) ou les surfaces incurvées composées d'arcs d'environ un quart de cercle. Les première à troisième faces de référence de montage (29a -29c) sont amenées à venir en butée contre les faces en forme de V des première à troisième faces à encoches (48a - 48c) de la partie de maintien (18), respectivement, pour ainsi positionner le miroir à face incurvée libre (14).
