Zygo's Verifire series of laser Fizeau interferometers represent a complete line of high performance metrology instruments for the measurement of plano, spherical and aspherical surfaces and material characteristics. The systems provide a variety of proprietary acquisition techniques to ensure optimum metrology in a wide range of environments.
The Verifire XL interferometer is a stand-alone workstation designed for simplistic and reliable metrology of large flat surfaces up to twelve inches (300 mm) in diameter. Examples include front-surface reflectors, windows, and semiconductor wafers or wafer chucks.
ZYGO's Verifire HD interferometer system provides fast high-resolution measurements of flat or spherical surfaces, and transmitted wavefront of optical systems and assemblies. The interferometric cavity length is precisely modulated while a high-speed camera captures several fringe images, which are analyzed by the software to create a highly detailed measurement of the part being tested.
ZYGO's Verifire interferometer system provides fast high-precision measurements of plano or spherical surfaces, and transmitted wavefront of optical systems and assemblies. Measure glass or plastic optical components - like flats, lenses, and prisms - and even precision machined metal and ceramic surfaces.
The new Zygo DynaFiz dynamic 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.
Verifire MST - wavelength shifting laser for simultaneous measurement of the front and back surface of transparent optics, thickness variation, wedge and 2-step homogeneity.The Verifire MST can measure two-, three- and even four-surface cavities. Show all of the surfaces, or only the surfaces of interest, within the MetroPro software. Artifacts are naturally suppressed using FTPSI, eliminating the need for an extended source.
