Abstract
A camera comprising various arrangements for employing optical elements in association with photosensitive elements are described. In some of the arrangements, the optical elements are formed integrally with a substrate containing the photosensitive elements. In other arrangements, an optical element is mounted to a package, or the like, containing the substrate and photosensitive elements. In other arrangements, two or more optical elements are employed, including conventional refractive elements, refractive focusing elements, and refractive beam splitting elements. Utility as solid state image sensors is discussed. Utility for monochromatic and color imaging is discussed. Various devices based on such camera arrangements and methods of making same are discussed.
