The new Zygo DynaFiz™ laser interferometer is a highly optimized optical instrument designed specifically for performing accurate metrology of optics in the presence of air turbulence and extreme vibrations. The high light efficiency of the DynaFiz™ optical system, combined with its long life, high power, HeNe laser source, enables operation at high camera shutter speeds that "freeze" vibration. This dynamic capability provides reliable metrology in environments that are too violent for traditional temporal phase shifting techniques.

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.
