Abstract
A plate of a deformable optical material is pressed against a rigid surface furrowed with a congruent network of alveoli by subjecting the two faces of the plate to fluid pressures of different values, the pressure on the face opposite the alveolate surface being less than the pressure on the other face of that plate. The alveoli are deeper than the thickness of the convex part of the microlenses formed therein by permanent deformation of the plate under the applied pressure.
