DEVICE FOR ACQUIRING AND MEASURING GEOMETRIC DATA OF AT LEAST ONE OPTIC GLASS-ASSOCIATED PATTERN AND ASSOCIATED METHOD

摘要

The device (22) is for acquiring and measuring geometric data of at least one pattern associated with an optical eyeglass lens (14) for the production of glass-like ophthalmic lenses. (14) or complementary. It comprises: - a frame (24); - a support (26) adapted to carry the glass (14); - a plate (28) connected to the support (26) and mounted on the frame (24); - Lighting means (30) of this plate (28); a video system (32) oriented towards the plate (28) and adapted to produce a video signal representative of at least one pattern associated with the glass (14) placed on the support (26); and - analysis and signal processing means (34) receiving as input the video signal produced by the video system (32), - means for moving the plate (28) relative to the frame (24) adapted to make taking from an axis normal to said platen (28) any desired orientation relative to a vertical direction of the frame (24); and means (40) for actuating said moving means.
