A method and apparatus for fabricating a multi-layer optical article includes grasping an outer surface of a first substrate with a first holder, whereby the outer surface of the first substrate is held to an inner surface of the first holder, grasping an outer surface of a second substrate with a second holder, whereby the outer surface of the second substrate is held to an inner surface of the second holder, arranging the inner surfaces of the holders to face one another, arranging at least one spacer element between the holders, disposing an adherent on the inner surface of one of the substrates, moving the holders together such that the holders contact the at least one spacer and the substrates contact the adherent, and at least partially curing the adherent while the inner surfaces of the holders are in a selected angular relationship. |
