Beverage, J., et al. “Interferometric Metrology for the TMT Primary Mirror Segments: Design and Analysis.” Optical Fabrication and Testing. Optica Publishing Group, 2019.

Abstract:

The Thirty Meter Telescope uses a hyperboloidal f/1 primary mirror made from 492 1.4-m segments with 82 different aspheric prescriptions. Each segment will be measured using Fizeau interferometry with spherical reference surface and CGH aspheric correction.
