Abstract
A holder member (32) is made with a configuration of indentations (33) corresponding to the indentations (24, 25) on a substrate (23) within which optical elements (11-14, 16-19) are to be bonded. Vacuum channels (34) are made in the holder member, each communicating with one of the holder indentations (33), through which a vacuum is applied to temporarily hold the optical elements in place. The substrate containing the indentations or grooves within which optical elements are to be bonded is then positioned above the optical elements mounted in the holder member (FIG. 8). The optical elements are simultaneously bonded to the substrate by lowering the substrate to contact the elements to effect the bond. After bonding, the holder vacuum is released and the substrate (23) is withdrawn with all of the optical elements (11-14, 16-19) bonded to it.
