Spectroscopic Ellipsometry -

Can resolve the individual properties of many stacked layers simultaneously.

Used to characterize 2D materials like graphene, where layers are only a few atoms thick. Spectroscopic Ellipsometry

Can detect films thinner than a single nanometer. Can resolve the individual properties of many stacked

The versatility of SE makes it indispensable across multiple high-tech industries: Spectroscopic Ellipsometry

In the world of material science, "seeing" is often a matter of interpretation rather than direct observation. is a premier non-destructive optical technique that serves as the "eyes" of researchers working with thin films and complex surfaces. By measuring how light changes its polarization state upon reflection, SE allows scientists to determine material properties—like thickness and refractive index—with atomic-scale precision. The Core Principle: Beyond Simple Reflection
