Join us in Copenhagen, Denmark, July 7-10 to see our latest optical interferometer innovations!
Stop by booth #219 where we will be showcasing our PhaseCam and NanoCam; and bring your samples by to get measurements right on the show floor!

PhaseCam: vibration-immune Twyman-Green interferometer with high power for measuring large optics and systems, and for long measurement paths. Its super-fast single-frame data acquisition enables measurement despite vibration and turbulence
NanoCam HD: a small, non-contact optical profiler for vibration-immune roughness measurement in challenging conditions
