Phasecam Laser Interferometers

4D Technology announces its new series of PhaseCam laser interferometers for accurate surface and wave front measurements at 1.053, 1.064, 1.3 and 1.55-micron wavelengths. PhaseCam laser interferometers employ "dynamic interferometry" technology to acquire measurement data in less than 30 microseconds. Because acquisition time is so short, the instruments are insensitive to vibration and air turbulence, enabling use in difficult environments such as production floors, clean rooms and environmental testing chambers. Beam Ratio adjustment ensures maximum fringe contrast, enabling measurement of optics with reflectivity from 1 - 100%. Turnkey PhaseCam NIR systems include 4Sight advanced wave front analysis software, providing extensive 2D and 3D 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 family provides accurate wave front quality measurement of optical elements from DUV through 10.6-micron infrared wavelengths.
