Zygo - Machined Structures

ZYGO serves our Semiconductor, Industrial, and Research customers by providing non-traditional glass and low-expansion components and systems which fall outside of the traditional definition of “optics”. Examples include light-weighted wafer stages for semiconductor lithography, zero-expansion metrology reference frames for precision positioning control, and traditional straight-edge mirrors and references. We routinely manufacture these items in sizes up to 1.25 m with nanometer precision (when required!).
