providing a deposition substrate other than the article surface, wherein
the deposition substrate is made of a removable material; thereafter
depositing the optical coating onto the deposition substrate, wherein
the optical coating has a first face contacting the deposition substrate, and a
second face remote from the first face; thereafter
transferring the optical coating to the article surface using a transfer
support; thereafter
affixing the optical coating to the article surface using a ceramic-
containing bonding element by pressing the optical coating and the article
surface together with the bonding element therebetween at an elevated
temperature; and thereafter
removing the transfer support.
