1. Device for making a composite lens (10) partly of mineral material and partly of organic material comprising, for moulding a mass of organic material into a sandwich between two performed layers of mineral material (12A, 12B) of which each one is at least partly supported by a complementary backing member (13A, 13B), an alignment tube (14) characterized in that each of the two layers (12A, 12B) of mineral material is formed by a film of reduced thickness, for example between 0.1 and 0.5 mm, and the backing members (13A, 13B) are complementary internally with the alignement tube (14) for contact therewith. |
