At the heart of every laser interferometer instrument is a laser source that enables a host of capabilities and features.

ZYGO's patented QPSI™ technology is truly a breakthrough in precision optical testing – it eliminates noise and ripple in phase data due to small vibrations, providing reliable data that would otherwise be noisy with traditional PSI acquisition. QPSI measurements require no special setup or calibration, and cycle times are typically equivalent to standard PSI measurements.

Interferometric optical measurements in dynamic environments – from extreme vibration to real-time optical system alignment.
