ANALYSIS, TEST AND MEASUREMENT
16 July 2008
Laser Physics has launched the FizCam 3000 from 4D Technology, a Fizeau interferometer developed for accurate measurement of meter-class optics and general optical elements.
Unlike traditional phase-shifting interferometers, which typically require hundreds of milliseconds per measurement, the FizCam 3000 utilises Dynamic Interferometry to acquire all measurement data in less than 1ms. Because acquisition time is so short, the FizCam is insensitive to vibration and air turbulence, enabling use in difficult environments without additional isolation. The system's completely on-axis design eliminates the inherent aberrations, software corrections and alignment typical of tilted beam Fizeau systems.
The FizCam 3000 is a turnkey instrument that includes the interferometer, 4Sight advanced wavefront analysis software, and complete high-speed computer system. In addition, the system offers true 4x motorised optical zoom imaging, and remote control of focus and zoom.
4Sight wavefront analysis software, included with the FizCam 3000, provides extensive 2D and 3D analysis and visualisation tools, as well as comprehensive filtering, masking, database and import/export functions.
The FizCam 3000 is ideally suited for metrology of large optical elements, especially those requiring long measurement paths where turbulence can be a significant challenge. The system is also designed for general optics testing and excels in noisy environments such as production floors, clean rooms and environmental testing chambers.
