ABSTRACT:
An optical device includes a transparent substrate, a first replicated refractive surface on a first surface of the substrate in a first material, and a second replicated refractive surface on a second surface, opposite the first surface, and made of a second material, different from the first material. The material and curvature of the first replicated surface and the material and curvature of the second replicated surface may be configured to substantially reduce the chromatic dispersion and/or the thermal sensitivity of the optical device.
