In this interview, Dr. Erik Novak, from 4D Technology TM, talks to AZoM about 4D dynamic interferometry. To begin, can you give us an introduction to what dynamic interferometry is and how it can be ...

A Linnik interferometer microscope is designed to take high-resolution images of the surface topography of a sample. The device works by splitting a beam of illuminating light in two, with one beam ...

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 ...

Lasers are often used to look at objects in microscopes. But even the best laser has “quantum noise” that makes a picture blurry and hides the details. This in turn results in measurements that are ...

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 ...
