Phasics offers a full range of wavefront measurement systems and quantitative phase imaging solutions based on an innovative high-resolution wavefront sensing technology. Phasics' unique patented wavefront sensing technology is called quadriwave lateral shearing interferometry (QWLSI). This technology offers ultra-high resolution (up to 852×720 measurement points), high sensitivity (sub-nanometric) and large dynamic range (hundreds of microns).

Moreover, Phasics' wavefront sensors are compact, achromatic, and easy to use thanks to their capability to perform direct measurements with no relay optics even on highly diverging beams. Phasics' core competency stands in both wavefront measurement and analysis with quadriwave lateral shearing interferometry.
