1. A monolithic lens optical arrangement for an array camera comprising: at least one lens element comprising: a first monolithic lens having front and back optical surfaces disposed on opposite sides of the first monolithic lens, wherein the front surface of the first monolithic lens has one of either a concave or convex profile, and wherein the back surface of the first monolithic lens has a plano profile; at least one aperture disposed on the back surface of the first monolithic lens and in optical alignment therewith; a second monolithic lens having front and back optical surfaces disposed on opposite sides of the second monolithic lens, wherein the front surface of the second monolithic lens has a plano profile, and wherein the back surface of the second monolithic lens has one of either a concave or convex profile, and wherein the second monolithic lens is arranged in optical alignment with said aperture; and wherein the back surface of the first monolithic lens element is in direct contact with the aperture and the front surface of the second monolithic lens forming a planar interface therebetween.
