A lens array and a method for fabricating a lens array that is relatively flat
and has useful lenses with relatively uniform sag heights are described herein.
In one embodiment, the lens array includes a one-dimensional array of useful lens
and two sacrificial lens each of which is formed next to an end of a row of the
useful lenses. In another embodiment, the lens array includes a two-dimensional
array of useful lens and a plurality of perimeter sacrificial lens each of which
is formed next to an end of a row or a column of the useful lenses. In yet another
embodiment, the lens array includes an array of useful lenses and a glass region
(including possibly a glass matrix) located within a opal border and outside a
opal region that surrounds the useful lenses.
