| abstract |
Methods, systems, and processes are used to prepare strong, durable, light-weight, mirrors, aspheric mirrors, disk drives and component parts using polymer-derived ceramics (PDCs), such as silicon oxycarbide (SioC) as a substrate for the mirror blank or disk drive. Very high performance mirrors and machine components are produced at much lower costs; thus increasing their usage in applications as varied as extra-terrestrial space applications to machine vision used by robots to stationary terrestrial mirrors and machines. |
