The new range of VeriFire™ interferometers from Zygo provide the next-generation interferometer family. Zygo has recreated the interferometers for the highest level of commercial performance and the fastest methods to acquire results. Combining unique illumination, revolutionary data acquisition, and a finely tuned electro-optical imaging system, the VeriFire range provides you with the technical excellence you expect from Zygo. The VeriFire series can measure aspheric surfaces; flat, parallel and optically transparent parts; surfaces and transmitted wavefronts with tight slope requirements.

The GPI family of laser Fizeau interferometers provides high speed, non-contact measurement capabilities for flat or spherical surfaces, and transmitted wavefront measurement of optical components and assemblies. The GPI is able to measure surface form and departure from spherical and flat surfaces to a very high precision and with traceability to certified standards.

The PTI 250™ line is a family of 25-mm aperture laser Fizeau interferometers that provide full 3D surface and wavefront maps, and radius of curvature measurements, of lenses and lens systems. These systems are Fizeau interferometers and are designed and built using the same successful methods as Zygo's widely used GPI™ and VeriFire™ interferometer systems.

FlashPhase is a new product from Zygo that enables measurements to be made using just one frame of interference pattern information to make the measurement. As such, FlashPhase offers advantages over the standard methods of measuring surface form and transmitted wavefront where vibration is present.
