Abstract
An improved procedure for manufacture of optical replication products comprising the use of a thin amorphous coating of carbon as a protective coating which also facilitates release during replication, between master and replication members. Particular attention is given to controlling the compressive forces of the carbon layer to provide good mechanical coatings on suitable optical surfaces. Thereafter, the replicated members may themselves be coated with the carbon as a protective coating only or for further use as a release-promoting 'submasters'.
