Abstract

SISTEMA PARA MARCAÇÃO DE UMA LENTE OFTÁLMICA REVESTIDA. Trata-se de um sistema para marcar um artigo óptico revestido (10) que tem pelo menos uma primeira marca (18) em uma superfície de um substrato (20) do artigo óptico revestido (10) que inclui pelo menos um dispositivo de identificação de marca (18) que tem pelo menos uma fonte de radiação eletromagnética (111) configurada para irradiar pelo menos uma porção da superfície do substrato (20) que tem a pelo menos uma primeira marca (18) com radiação eletromagnética (119A, 123). O pelo menos um dispositivo de identificação de marca (18) inclui adicionalmente pelo menos um dispositivo de imageamento configurado para receber uma porção da radiação eletromagnética (119A, 123) refletida da superfície do substrato (20) que tem a pelo menos uma primeira marca (18) e determinar uma posição da pelo menos uma primeira marca (18) na superfície do substrato (20). O sistema inclui adicionalmente pelo menos um dispositivo de marcação configurado para marcar o artigo óptico revestido (10) com pelo menos uma segunda marca (180) com base na posição da pelo menos uma primeira marca (18).
