A telecentric lens (100) comprises a front optical group (112) adapted to receive the rays coming from an object observed and a rear optical group (114) adapted to convey said rays towards a sensor (30). At least one between the front optical group (112) and the rear optical group (114) consists of only two positive focal lenses (112; 114′). An artificial vision device (1) comprises the telecentric lens (100) and a lighting device (20) having a paraboloidal semi-reflector element (22). |
