The technique of fabrication by epoxy replication is used for the production of quality diffraction grating. This technique is being applied to producing a widening variety of optical components. In this paper we report experimental result of the production of convex aspheric by replication. We employ this method by difficulties of generation and test of convex aspheric in a optical workshop. Employing the replication we obtain convex surfaces with good quality. The aspheric produced are used as secondary mirror in telescopes. We present initial experimental replication of a reflective hyperbolic mirror.
