Abstract
Improved lens, of the type consisting of a spherical cap of reduced thickness, of the so-called "negatives", characterized essentially by the fact of presenting its faceted outer face in concentric circles, whose facets are perpendicular in all points to the imaginary lines that join each of them with the center of curvature of the lens or with any point of the axis of symmetry; because in the case of a spherical lens, all the points of the same height or elevation are carved by the same plane, the resultant being a circumference; because in the so-called "positive" lenses the circular facets are practiced on their inner face; and because if the lens is of the so-called "cylindrical" the facets would be longitudinal.
