Abstract
A microlens array has a plurality of microlens supportedly arranged on a first surface of a transparent medium. At least two optical features are formed on a second surface opposite the first surface. Fiducial marks are formed on the second surface by a beam of collimated light directed onto the optical features and focused onto the second surface. Fiducial marks enable precise alignment of the microlenses in the microlens array.
