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.

Abstract
A variety of optical arrangements and methods of modifying or enhancing the optical characteristics and functionality of these optical arrangements are provided. The optical arrangements being specifically designed to operate with camera arrays that incorporate an imaging device that is formed of a plurality of imagers that each include a plurality of pixels. The plurality of imagers include a first imager having a first imaging characteristics and a second imager having a second imaging characteristics. The images generated by the plurality of imagers are processed to obtain an enhanced image compared to images captured by the imagers.
