Qualifire Interferometers - Next Generation Metrology

The new Qualifire® Laser Interferometers from Zygo are the next generation of non-contact metrology. These interferometers provide fast and reliable measurements of surface form error and transmitted wavefront of optical components, systems, and assemblies. They build on Zygo's long history as a pioneer in phase-shifting interferometry while adding new features that improve ease of use including: Coherent Artifact Reduction – removing coherent spatial noise and annoying coherent bullseye artifacts using Flying Spot for the best signal to noise ratio possible Plano Cavity Autofocus – a very precise focus can be set on perfectly specular surfaces without the need for edges, fiducials, reticles, or other physical artifacts necessary for manual or intensity-based focus, all without operator intervention Stable Zoom – stable optical alignment so that there is no shift in focus or image centering from 1X to 3X zoom and no loss of fidelity. Smart Accessories – automatically sets the instrument lateral resolution based on the accessory installed and, for Smart Transmission Spheres, the radius of curvature of the part. Then, an on-board factory calibrated system error map is automatically fit and subtracted from measured data, enabling the best metrology on the market with a reduced setup time This video shows our two Qualifire demos from the SPIE Photonics West 2026 tradeshow, highlighting both the general purpose Qualifire 1.2+ Laser Interferometer and the short coherence length Qualifire 2.3 Laser Interferometer for measuring multiple parallel surfaces.
