ABSTRACT:
A method of improving aspects critical to the reflector making process by defining a reflector surface definition of specularity by its solid angle measurement and a repeatable execution process. The controlled specularity on a hardened steel tool is replicated on a reflector by forcing the reflector surface to yield in extra compression yield failure and permanently set the desired specularity in the reflector. Next, a physical as well as analytical model of the reflection behavior, based on the solid angle geometry, is provided.
