Paper Abstract

Precision aspheric surfaces can be produced by Thin Film Epoxy Replication for operation in the ultra-violet, visible and infrared spectral regions. Accuracies to 1/10 wave at 633 nm are obtained by proper control of the master, replica substrate and replication process. Aspherics with small deviations from the best fit sphere can use spherical substrates; otherwise aspheric substrates must be used. Aspheric mirrors up to 16 inch diameter have been produced to 1/4 wave accuracy. Off axis ellipsoids with deviations from the best fit sphere measured in fractions of an inch have been produced with surface accuracies of 1/4 wave per cm. in production quantities.
