Abstract

A lens (5) comprising a solid and transparent host material (6) containing therein a plurality of solid and substantially spherical or spheroid transparent particles (7) each fixed within the host material and collectively arranged therein to form a layer of such particles embedded immediately beneath a common surface (6A) of the host material such that a respective optical focus of each of the particles resides outside the host material.
