We suspect there are three kinds of people in the world. People who have access to a Michelson Interferometer and are glad, those who don’t have one and don’t know what one is, and a ...

MOST existing methods of calibrating vibration pick-ups employ some form of extrapolation, that is, the pick-up is calibrated at low frequencies, where the amplitude can be made large, and the result ...

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 ...

The need of highly accurate wavelength measurements necessitates calibration and long-term stability in the measuring instrument. For precise, continuous wavelength measurement, a continuous reference ...

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 ...
