Paper Abstract
Advanced Virgo is an upgrade to the Virgo detector located near Pisa, Italy designed with an ultimate goal of the
detection of gravitational waves originating from cosmic sources. The upgrade will provide an order of magnitude
increase in the sensitivity of the detector and allow the exploration of a volume 1,000 times larger than Virgo. The
system design includes 21 ‘half meter’ class optics for which Zygo has been selected as the primary supplier. The
optic components have nanometer level low-order figure requirements along with sub-angstrom roughness
requirements specified over a wide spatial frequency band. In this paper the results and methodologies used in
achieving such extreme requirements that are typically associated with the semiconductor lithography industry will
be presented.
