Proposal for a 1.8-meter metal mirror of meniscus shape at once actively aspherized at f/1.8 and actively supported

New aspherization methods have been developed and applied in the field of astronomical optics. These methods, based on the elastic properties of substrates, have been used separately as well during the polishing process as in situ as the telescope. The goal of this proposal is to combined for the first time, on a primary mirror of telescope, these two possibilities in order to achieve the best optical figure from active optics capabilities.© (1993) COPYRIGHT SPIE--The International Society for Optical Engineering.
