Ophthalmic lens reference characteristic e.g. centering characteristic, detecting device, has support with passive pointer that forms reference image on light acquisition and analysis units, when lighted by lighting unit

摘要

The device has a support (110) to receive an ophthalmic lens and movable in translation along two axes perpendicular. The support has a passive pointer (113) that forms a reference image on light acquisition and analysis units, when lighted by a lighting unit (120). An active pointer emits a signal received by the light acquisition and analysis units. The units acquire and analyze the light sent by the lens.
