Replicated optics can be used for both reflective and transmissive components. The main reasons for using replicated optics are to: Minimize system cost, Produce light weight or low inertia optics, Locate optical surfaces in otherwise inaccessible locationsFlat mirrors made of Pyrex or metal from 1 to 1/10 wave accuracy is a good application for replication. Mirrors made from float glass to 2 waves/inch irregularity that can be made by cutting up sheet stock and coating the front surface, will be cheaper to produce than the equivalent mirror made by replication. We have performed a qualitative comparison between replication, conventional polishing, single point diamond machining and electroforming.
