4D Technology's PhaseCam® IR interferometer provides accurate surface and wavefront measurements at the 3.39 micron wavelength.
The PhaseCam IR laser interferometer employs Dynamic Interferometry® to acquire measurement data in less than 1 millisecond. Because acquisition time is so short, the instruments can measure accurately despite vibration and air turbulence. The systems can be used in demanding environments such as clean rooms or the production floor. These dual-mode systems can also operate using traditional, temporal phase-shifting.
Turnkey PhaseCam IR systems include 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.
PhaseCam IR systems are ideally suited for quality verification of IR optics, including focal optical systems and afocal components.
