Abstract
An optical lens is secured to supporting setting platforms, of which one is formed by a circumferential sector conjugated with the optical element (lens) so as to form shoulders. The other of said platforms is formed by two rounded-off radial portions conjugated with each other and with the optical element. Both of the platforms have biconcave surfaces, and one of these is thicker than the other.
