PhaseCam Laser Interferometers for IR Wavelengths

4D Technology has introduced its new series of PhaseCam laser interferometers for accurate surface and wavefront measurements at IR wavelengths (3.39 or 10.6µm).

PhaseCam IR laser interferometers employ Dynamic Interferometry technology to acquire measurement data in less than one millisecond. Because acquisition time is short, the instruments can measure accurately despite vibration and air turbulence. This ability allows the systems to be used in difficult environments such as clean rooms and production areas. The dual-mode systems also operate using traditional, temporal phase-shifting interferometry.

Turn-key PhaseCam IR systems include 4Sight wavefront analysis software, providing 2D and 3D analysis and visualisation tools, as well as filtering, masking, database and import/export functions. The systems are suited for quality verification of IR optics, including focal optical systems and afocal components.
