Abstract

L'invention concerne un dispositif de mesure d'éléments à surface asphérique à symétrie axiale. Elle se rapporte à un dispositif qui comprend un dispositif 1 de montage d'un élément asphérique 2, un organe 7 de détection de rugosité monté sur un chariot 6 et un dispositif 14 de mise en action qui transmet un mouvement d'amplitude réduite au chariot 6 par l'intermédiaire d'un levier 8. Un dispositif 5 fait tourner le dispositif 1 de montage, et une commande 13 compare les déplacements du chariot 6 à des valeurs mémorisées. Application au contrôle d'éléments optiques asphériques.
