DEVICE AND METHOD FOR PREPARING AN OPHTHALMIC LENS FOR MACHINING

摘要

The invention relates to a device (1) for preparing an ophthalmic lens for machining, that comprises a holder (100) capable of maintaining said ophthalmic lens, blocking means (400) including at least one blocking accessory (450) and a handling arm (401) for said clocking accessory, an acquisition device (200) capable of acquiring an image of the ophthalmic lens, and electronic and/or computer processing means (700) capable, on the one hand, of deriving an optical reference of the ophthalmic lens and, on the other hand, of driving the handling arm and/or the holder in order to apply said blocking accessory against the ophthalmic lens in a given blocking position. According to the invention, the blocking means and/or the holder include at least one marking element and the electronic and/or computer processing means are adapted for identifying the position of said marking element on an image acquired by the acquisition means and in which an image of said marking element appears.
