ABSTRACT:
Formed by modules (1) with bi-convex (2) configurations in the central modules (1) of the lens, becoming plano-convex and finally concavo-convex in its end modules (1), with a smooth transition (3), all ridges or grooves being minimized, and with the vertical face joining the upper and lower facets of the modules (1) being flat and inclined towards the optical axis, eliminating spherical aberration by incorporating in the modules (1) refracting fluids with different refraction index and very small volume, in a construction with a minimal thickness and weight.
