The Intellium H1000 instantaneous phase-shifting Fizeau interferometer released by Engineering Synthesis Design Inc. (ESDI) is vibration-insensitive and captures events down to 10 µs. With a compact footprint of 7.5 × 13.5 in., the device is suitable for testing large optics (<24 in.) and for measuring machined parts and semiconductor wafers. The patented I-Phase module replaces the standard camera and produces three ultraprecise phase-shifted interferograms that are simultaneously acquired and processed into a 3-D surface map.
