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

Manufacturing of super-polished large aspheric/freeform optics
Autor: Kim, Dae Wook, Oh, Chang-jin, Lowman, Andrew, Smith, Greg A., Aftab, Maham, Burge, James H.
Several next generation astronomical telescopes or large optical systems utilize aspheric/freeform optics for creating a segmented optical system. Multiple mirrors can be combined to form a larger optical surface or used as a single surface to avoid
