ABSTRACT:
An imaging device is disclosed which comprises a noble metal photosensitive glass having formed on the surfaces a plurality of raised spherical surfaces which form an array of thick lenses. The array can be positioned between an object and image plane to project images from the object plane onto the image plane. Lens spherical aberrations are reduced and lens array imaging performance is optimized by an optimum lens aperture radius or an optimum lens numerical aperture.
