Zygo - Model Verifire MST + - Simultaneous Multi-Surface Test Interferometer - Brochure

Simplify the complex – multiple surfaces create complex fringe patterns, the Verifire™ MST uses patented wavelength-shifting technology to acquire phase data from multiple surfaces simultaneously.  Report key metrics from individual surfaces of parallel windows, transmitted wavefront, as well as precise surface-to-surface information like total thickness variation (TTV), wedge and even material inhomogeneity.
