Paper Abstract

The principle of replication of optical surfaces developed at OCA is given and positive results obtained in the double replication of a 1-m diameter concave master onto a concave substrate by means of an intermediate convex replica is presented. The effect of thermal cycles and humidity is addressed as well. The technology has potential applications which are not limited to serial production of small optical components but may ease the production of large convex mirrors, processing of lightweight substrates and possible exotic materials. Possible use of this technique for the VLT secondaries and/or Coude train will conclude.
