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.
