<p>A method of producing a desired surface (32, 34) on an optical material (26) including producing a plurality of elements (26) of the optical material such that each element (26) has an upper and a lower surface, arranging the plurality of elements (26) such that adjacent elements (26) are separated by an interstitial material (28) having a hardness different from the optical material being processed, processing the surfaces (32, 34) or the elements (26) and removing the interstitial material (28).</p> |
