Abstract
A microlens array diffuser operable to generate a substantially diffuse illumination includes an array of microlenses, wherein each microlens has a respective periodicity-influencing characteristic and a respective surface profile. The array of microlenses includes at least two microlenses having respective periodicity-influencing characteristics that differ from one another and having respective surface profiles that differ from one another. Each surface profile is configured to generate a substantially equal field of illumination. The microlens array diffuser can be integrated as part of an illuminator operable to generate substantially diffuse illumination.
