<p>An integrated micro-optical system (61) includes at least two wafers with at least two optical elements (71, 73, 75, 77) provided on respective surfaces (50, 52, 54, 56, 58) of the at least two wafers. An active element (63) having a characteristic which changes in response to an applied field may be integrated on a bottom surface (67) of the wafers. The resulting optical system may present a high numerical aperture. Preferably, one of the optical elements is a refractive element formed in a material having a high index of refraction.</p> |
