ZYGO's GPI family™ of interferometers are the industry standard for noncontact measurement of flat or spherical surfaces, and transmitted wavefront measurement of optical components and assemblies. (read more)

The PTI 250™ line is a family of 25-mm interferometers that provide full 3D surface and wavefront maps, and radius of curvature measurements, of lenses and lens systems. (read more)

FizCam dynamic Fizeau interferometers provide accurate, large aperture measurements even in challenging environments. FizCam systems capture full wavefront measurements in less than 1 millisecond, enabling accurate measurement even in the presence of vibration and air turbulence. (read more)

PhaseCam® NIR dynamic laser interferometers offer accurate surface and wavefront measurements at 1.053, 1.064, 1.3 and 1.55 micron wavelengths. PhaseCam laser interferometers acquire measurement data in less than 30 us, making them insensitive to vibration and air turbulence. Applications include measurement of optics for astronomy, surveillance, guidance and directed energy. (read more)

ZYGO's new artifact suppression technology practically eliminates the 'bullseyes' caused by spurious interference in standard point-source interferometers. Save analysis time and increase your measurement accuracy with this high-end metrology instrument. (read more)

The Lapmaster/LAMTech TOPOS and SPI series of Interferometers feature Grazing Incidence flatness inspection and measurement capability for grinding, lapping & polishing applications. The need to generate a polished surface, strictly for optical flatness measurement, is eliminated with the use of these systems. Ground surfaces, matte surfaces and polsihed surfaces can all be measured. (read more)

The DVD400 Interferometer System provides high-accuracy, noncontact, measurements of transmitted-wavefront quality of small lenses (1.5 - 6 mm). (read more)

The VeriFire MST™ provides results and measurement capabilities never before available. ZYGO's patented data acquisition methods enable simultaneous measurement of front and back surfaces, thickness variation (including wedge) and homogeneity of polished parallel plates. No part preparation or messy coatings are necessary. (read more)

Non-contact displacement and vibration sensor capable of ultra-high resolution of 0.08nm with high speed response. (read more)

PhaseCam dynamic Twyman-Green interferometers provide high resolution measurements that are insensitive to vibration and air turbulence. PhaseCams capture full wavefront measurements in as little as 30 microseconds—5000 times faster than conventional phase shifting interferometers. (read more)
