ADE Phase Shift was founded in Tucson as Phase ShiftTechnology, Inc. in 1987, by Chris Koliopoulos, Ph.D. and David Basila.The company soon offered a variety of interferometry-based products,including fringe analysis software, laser-based Fizeau interferometers,and microscope-based white light interferometers.
Interferometers use the natural wave properties of light, reflectedfrom a surface to be tested, to map the tiniest surface heightvariations. Using interferometry, telescope mirror manufacturers gaugethe quality and focus of their mirrors, and disk drive manufacturersmake sure the platters used in computer disk drives are flat enough towithstand the high speeds and close quarters of the interior of acomputer drive. It was Phase Shift interferometers that were used bythe company that made the lenses that fixed the orbital Hubbletelescope's blurred vision.
In 1998, Phase Shift Technology merged with Massachusetts-based ADECorporation, a manufacturer of metrology equipment for thesemiconductor and data storage industries. Since that time, the companyhas been called ADE Phase Shift.
ADE Phase Shift now makes products with applications for the measuringof the surface topology of polished silicon wafers, as well as systemsfor measuring critical surfaces in the hard disk industry, and manyneeds of optics manufacturers.
