4D Technology Introduces A New Dynamic Interferometer System With Twice The Spatial Sampling

Tucson, AZ – The new PhaseCam™ 4010 is a high performance, dynamic Tywaman Green interferometer system that offers twice the spatial sampling of the original PhaseCam from 4D. Unlike old style phase-shifting interferometers, the PhaseCam™ works by acquiring all of the information to compute phase in a single exposure and is vibration insensitive. The PhaseCam 4010 includes an innovative single camera and a high-speed optical phase sensor that eliminates the need for slow, bulky phase shifters and has the ability to acquire data in as little as 1msec.That is over 10,000 times faster than conventional temporal phase shifting interferometers. This new system still has all of the features and benefits of the original PhaseCam such as enabling precision measurements without the need of an isolation table, a simple standard Camera Link™ interface and a single mode, HeNe laser that eliminates mode hoping, and allows short exposure, and long life.

The PhaseCam 4010's insensitivity to vibration and air turbulence make if ideally suited for production floor quality control, optical metrology of large optical elements, astronomical optics and aerospace systems, clean room applications typically hampered by air flow turbulence, the use in vacuum and environmental chambers, and precise metrology on automated manufacturing machines such as polishers and diamond turning machines. Additionally, measurements of moving parts such as scanner mirrors, spinning disks, or vibrating membranes can all be performed easily with the PhaseCam 4010 and their dynamic modal behavior investigated. Major markets include aerospace, astronomy, optical fabrication, and adaptive optics.

This turn-key instrument includes the interferometer mainframe, a fast Pentium IV computer system and 4Sight™ software. Powered by a simple, intuitive user interface, this advanced wavefront analysis software from 4D Technology features an easy to use suite of options for measurement set-up, data analysis and graphical display of results. 4D also offers a wide variety of precision accessory optics for the PhaseCam, modal analysis software and has provided vacuum compatible, mutli-wavelength or ESPI system configurations.
