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.
An optical lens support comprising at least one first base, at least three bearing studs, carried by the at least one first base for holding an optical lens by its edge, said base having a planar bearing surface for seating the base and a globally circular peripheral contour, a radial dimension along any radius of the bearing surface being at least equal the axial dimension of said base perpendicular to the bearing surface thereof.
In a spin-coating apparatus including a turntable incorporating suction orifices, the improvement comprising an optical lens support, the lens support including at least one first base, at least three bearing studs, carried by the at least one first base for holding an optical lens by its edge, said base having a planar bearing surface for seating the base and a globally circular peripheral contour, a radial dimension along any radius of the bearing surface being at least equal the axial dimension of said base perpendicular to the bearing surface thereof, the planar bearing surface being cooperable with the turntable for holding the base on the turntable.
