439 Ellipsometer

DigiPol Technologies features the Elli-SE Spectroscopic Ellipsometer.

For diverse applications, the Elli-SE Spectroscopic Ellipsometer is available in a wide range of configurations.

Elli-SE Spectroscopic Ellipsometer

Elli-SE Spectroscopic Ellipsometer (SE) is the industry standard technology that enables one to accurately measure thickness and optical constants of thin film, simultaneously. It is used for the characterization of a variety of materials (e.g., dielectrics, semiconductors, organics, etc.) including AR coatings, OLED, and low (high) -materials.

Specifications Elli-SE


  • Measuring constants: Film thickness, n, kvs λ
