Optics Valley is a region in southern
Arizona, centered on
Tucson, that is home to a high concentration of
optics companies spawned by research at the
University of Arizona. Based on the idea of a technology cluster such as
Silicon Valley, Optics Valley is known not only for its optics industry and research but also for the
astronomical observatories located in the mountains of southern Arizona where clear skies and isolated peaks make for superior observing conditions.
