4DTechnology.jpgFor surface and wavefront measurements at 3.39- or 10.6-μm wavelengths, 4D Technology Corp. has introduced the PhaseCam laser interferometers. Using Dynamic Interferometry technology, the devices acquire measurement data in <1 ms, despite vibration and air turbulence. The dual-mode systems also can operate using traditional temporal phase-shifting interferometry. The turnkey infrared systems include 4Sight wavefront analysis software that provides 2- and 3-D analysis and visualization tools as well as filtering, masking, database and import/export functions. They are suitable for verifying the quality of infrared optics, including focal optical systems (concave telescopes and lens systems) and afocal components (flat mirrors and collimators).
