Abstract
A process is disclosed for fabricating multi-faceted scanner mirrors, such as for use in visible light or infrared scanner, which advantageously provides improved optical quality and significant manufacturing time and cost savings over prior art processes by rough-forming the complete mirror with a plurality of facets, severing individual facets, polishing the severed facets, and reassembling the facets into a complete mirror.
