ZYGO Verifire™ MST Laser Interferometer
Verifire™ MST laser interferometer enables precise optical metrology of multiple surfaces simultaneously, including plane parallel components with multiple reflections.
The Verifire™ MST starts with the classical interferometer applications. These applications all measure the wavefront variations between two surfaces, a two-surface cavity. However, measuring an uncoated parallel plate gives two layered interferograms (a three-surface cavity) that confuse standard Phase Shift Interferometry algorithms.
