The MSC WLI white-light interferometer measures surface parameters such as profile, roughness, step height, and microstructure without damaging the target. Its light source is a high-brightness LED ...

Interferometers, devices that can modulate aspects of light, play the important role of modulating and switching light signals in fiber-optic communications networks and are frequently used for gas ...

White light interferometry (WLI) is a contact-free optical method for measuring surface height. It uses the phase difference between the light reflected off a reference mirror and the target sample to ...

Electronic and computer processors with a higher speed need smaller features for integrated circuits (IC), which also need smoother and smaller substrate surfaces. Chemical mechanical polishing (CMP) ...

A team of scientists has managed to successfully perform atom interferometry in space - on board a sounding rocket. Extremely precise measurements are possible using atom interferometers that employ ...
