  • Patent number: 6842299
    Abstract: An individual carrier for an optical lens comprising, in a plastics one-block single part as directly molded: a globally ring-shaped base (1) with a central axis (100) and a median plane perpendicular to such a central axis, at least three plots (2, 3, 4; 52, 53, 54) projecting from the internal edge (5) of the base (1) for holding the lens through its edge, at least one (4) of such plots being resiliently moveable in translation along a radial direction (101) relative to said axis, between an internal rest position and a range of active external positions, a spring (6, 7) arranged between the moveable plot (4) and the base (1) for exerting a resilient return stress of the moveable plot (4) towards its rest position.

  • Patent number: 6473247
    Abstract: The invention concerns a support of the type comprising at least a first base (13), and, borne by the latter, for maintaining such an optical lens (10) at its edge (11), at least three support pins (14A, 14B). The invention is characterized in that the base comprises, for its own support, a plane support surface (16) whereof the peripheral outline (P1) is globally circular, its radial dimension (D1) along a particular radius (R) of said support surface (16) is at least equal to its axial dimension (D2) perpendicularly to the plane thereof. The invention is particularly useful for maintaining an optical lens in a processing apparatus using spin coating technique.
