4D Technology's PhaseCam® IR interferometer provides accurate surface and wavefront measurements at the 3.39 micron wavelength.
The PhaseCam IR infrared interferometer employs Dynamic Interferometry® to acquire measurement data in less than 1 millisecond. Because acquisition time is so short, the instrument can measure accurately despite vibration and air turbulence. The system can be used in demanding environments such as clean rooms or the production floor. The dual-mode system can also operate as a traditional, temporal phase-shifting infrared interferometer.
The PhaseCam IR includes 4Sight™ advanced wavefront analysis software, providing extensive 2D and 3D analysis and visualization tools, as well as comprehensive filtering, masking, database and import/export functions.
The PhaseCam IR infrared interferometer is ideally suited for quality verification of infrared optics, including focal optical systems and afocal components.
