Static liquid interface production of lenses and other contoured objects

A method of producing at least one object having a contoured surface portion, comprising:

• (a) providing a first window containing an inhibitor of polymerization,
• (b) coating said first window with a light polymerizable resin under conditions in which said inhibitor passes into a portion of said light polymerizable resin and thereby forms a first dead zone of unpolymerizable resin contacting said first window;
• (c) exposing said light polymerizable resin to patterned polymerizing light through said first window at a first light dosage sufficient to form said object in said light polymerizable resin under stationary conditions, while
• (d) spatially modulating said first light dosage so that said first dead zone is spatially contoured in thickness to produce a first contoured surface portion on each said object, which the first contoured surface portion is in contact with said first dead zone of unpolymerizable resin,
• (e) contacting a second window to said resin in a position opposing said first window, said second window containing an inhibitor of polymerization, under conditions in which said inhibitor of said second window passes into a portion of said light polymerizable resin and forms a second dead zone of unpolymerizable resin contacting said second window;
• and
• (f) further exposing said light polymerizable resin to patterned polymerizing light through said second window at a second light dosage sufficient to further form said object in said light polymerizable resin under stationary conditions;
• while
• (g) spatially modulating said second light dosage so that said second dead zone is spatially contoured in thickness to produce a second contoured surface portion on said object, which said second contoured surface portion is in contact with said second dead zone of unpolymerizable resin.
