Modern technologies of fabrication and testing of large convex secondary mirrors

Autor: Oh, Chang Jin, Lowman, Andrew E., Dubin, Matt, Smith, Greg, Frater, Eric, Zhao, Chunyu, Burge, James H.

Modern large telescopes such as TAO, LSST, TMT and EELT require 0.9m-4m monolithic convex secondary mirrors. The fabrication and testing of these large convex secondary mirrors of astronomical telescopes is getting challenging as the aperture of the
