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 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 ...

The form of orthopedic implants can broadly vary. These variations can occur in terms of size (from millimeters to tens of centimeters), shape (from complex saddle-shaped knee prostheses to simple ...

Stacking chips is making it far more difficult to find existing and latent defects, and to check for things like die shift, leftover particles from other processes, co-planarity of bumps, and adhesion ...
