White-light interferometry is one of today’s most precise tools for determining the properties of optical materials. Its achievable precision and accuracy are typically limited by systematic ...

White light interferometry (WLI) and its variant, coherence scanning interferometry (CSI), are advanced optical techniques used for high-precision surface profiling and measurement. These methods ...

It utilizes various principles such as interference, reflectance, or shadowing to capture the three-dimensional topography of the surface. Techniques like white light interferometry (WLI) and confocal ...

The hybrid instrument is an undispersed Michelson interferometer having a fixed delay of about 1 cm, in series with an external spectrograph of about 20,000 resolution. The Michelson provides the ...
