Abstract

L’invention concerne un profilomètre (1) pour surface optique (So), comportant un bâti (2),des capteurs de distance (6), montés sur un support de capteurs (3) pour mesurer chacun une distance selon un axe de mesure (9) localement sensiblement normale à une surface de montage (5) du support de capteurs (3), etun support d’élément optique (10) pour maintenir une surface optique (So) d’un élément optique (Eo) à mesurer en regard des capteurs de distance (6) et du support de capteurs (3), la surface de montage (5) étant incurvée pour être complémentaire d’une surface de référence incurvée d’un élément optique de référence maintenu en regard du support de capteurs (3), la surface optique (So) de l’élément optique (Eo) à mesurer étant théoriquement identique à la surface de référence de l’élément optique de référence.
