Abstract

No matter how a high precision optical element is manufactured, "replication" most likely offers a lower cost method to produce it in quantity. All parts made from the same master are essentially matched sets and identical in all their characteristics, a feat which would be very expensive to attempt in any other manufacturing method. Any substrate material which will satisfy the mechanical design requirements, can be optically surfaced by thin film replication. From a dozen space flight ultra light weight telescopes to high production military components, to a steady flow of commercial and instrument quality mirrors, "replication" has proven its cost effectiveness and overall viability. This paper will discuss a cross-section of reflective components which are representative of the thousands used every year by the optical industry.
