ABSTRACT:
A thin film plastic is centrifugally cast against an aluminum preform which is placed in a precisely machined polygonal master in a conventional replica process. The plastic which may be an epoxy material is applied to the preform master assembly with centrifugal force causing it to impact in the cavity between the preform and the master to produce a bubble-free layer. Thus, a high speed multifaceted polygonal scanning system is provided which may be employed in a flying spot scanning application.
