23. A lens array, comprising:
a first surface, and
a second surface including:
lens facets, and
translation edges, each translation edge extending between two lens facets,
wherein, for each respective translation edge of a first plurality of the translation edges, a cross-sectional profile of the respective translation edge of the first plurality of the translation edges is angled at a first angle relative to a first plane, and
wherein, for each respective translation edge of a second plurality of the translation edges, a cross-sectional profile of the respective translation edge of the second plurality of the translation edges is angled at a second angle relative to a second plane, the second angle being less than the first angle, wherein the first plane and the second plane are perpendicular to the first surface.
