TUCSON, Ariz., June 16, 2008 -- 4D Technology Corp.'s new series of PhaseCam laser interferometers are designed for accurate surface and wavefront measurements at wavelengths of 1.053, 1.064, 1.3 and 1.55 µm.

PhaseCam laser interferometers employ a "dynamic" interferometry technology to acquire measurement data in less than 30 microseconds, 4D Technology said. Because acquisition time is so short, the instruments are insensitive to vibration and air turbulence, enabling use in difficult environments such as production floors, cleanrooms and environmental testing chambers. Beam ratio adjustment ensures maximum fringe contrast, enabling measurement of optics with reflectivity from 1 to 100 percent.

Turnkey PhaseCam near-infrared (NIR) systems include 4Sight advanced wavefront analysis software, providing extensive 2-D and 3-D analysis and visualization tools, as well as comprehensive filtering, masking, database and import/export functions.

Applications for PhaseCam NIR systems include measurement of optics for astronomy, surveillance, guidance and directed energy. The PhaseCam line provides accurate wavefront quality measurement of optical elements from deep ultraviolet through 10.6-µm infrared wavelengths, 4D Technology said.
