Diffraction International does not sell or manufacture interferometers. Instead, we provide software and hardware to work with any commercial or shop-built interferometer. If you don't see what you need here, please let us know and we will do our best to meet your needs. We have made Durango Interferometry Software work with most of the popular commercial interferometers.
 Fizeau Phase Shifter adds Durango phase measuring capability to your 4-inch Fizeau interferometer.   PZT Linear Stage adds low voltage phase shifting to any small interferometer. Use it to translate either the reference surface or the optic under test. 
For a turnkey solution, Diffraction International offers Dell and Lenovo ThinkPad computers with all required boards and software installed and configured. Other Supported Hardware:
