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 ...

Scientists needing to make sensitive displacement measurements will benefit from a simple way to increase the resolution of an interferometer. Researchers in France have discovered a clever way to ...

The resolution of an interferometer is dependent on the linewidth of the illuminating laser, wavelength stability and its absolute wavelength. UniKLasers introduce a range of single frequency lasers ...
