Method and apparatus for multilayer optical articles

一种用于多层光学制品的方法和装置。方法包括用第一夹具(100)和第二夹具(102)形成第一多层制品，所述多层制品具有第一衬底(104)，第一粘合剂(110)和第二衬底(106)。方法还包括形成第二多层制品，所述第二多层制品具有第一多层制品，第二粘合剂(112)和第三衬底(114)，同时用第一夹具(100)和第二夹具(102)来夹紧第二多层制品。在除去第一夹具(100)和第二夹具(102)之后，第一粘合剂(110)和第二粘合剂(112)使第二多层制品保持处于第二多层制品被第一夹具(100)和第二夹具(102)保持时的姿势，其中第一粘合剂(110)和第二粘合剂(112)包括光聚合物，以便制品能将数据存储在反射式全息数据存储系统中。 The present invention provides a method and apparatus for a multilayer optical articles. A method comprises forming a first multilayer article with a first substrate and a second substrate with a first adherent disposed between the first and second substrate. A first surface of a third substrate is then grasped with a first holder and a second adherent is then disposed on one or more surfaces selected from a second surface of the third substrate and a surface of the first multilayer article while the multilayer article is grasped by a second holder. The second adherent is then at least partially cured while the first and second holders maintain their grasp and while the inner surfaces of the first and second holders are in the selected angular relationship to form a second multilayer article.
