Claim:
A method for spin coating a surface of an optical article, comprising: selecting as said optical article an article ( 10 ) with a concave face ( 12 ) able to adopt a facing up position with an edge ( 15 ) at an uppermost portion of the concave face ( 12 ), and selecting said concave face ( 12 ) as said surface to be coated; dispensing a predetermined volume of a coating solution on said concave face ( 12 ), said coating solution being dispensed only to an area along an entirety of said edge ( 15 ), said concave face ( 12 ) facing up and said coating solution being dispensed to said edge ( 15 ) in a top down manner; immediately after said dispensing step, waiting with no motion of said article ( 10 ) for said coating solution to flow on said concave face ( 12 ) until said coating solution collects at a location at a center of the concave face ( 12 ); and after said waiting step, spinning said article ( 10 ) to force the coating solution back to the edge ( 15 ) of the concave face ( 12 ).
