Ellipsometers and Reflectometers

FilmTek SE

A streamlined option for precise, repeatable spectroscopic ellipsometry

FilmTek SE

The base model of our "SE" product line, the FilmTek™ SE automated benchtop spectroscopic ellipsometer offers users a streamlined option for quickly and easily collecting highly precise, repeatable measurements on a range of thin and ultra-thin film samples.


This system enables fast, accurate, uncomplicated measurement of film thickness, refractive index, and extinction coefficient with a measurable thickness range of <1 Å to 50 µm. It is capable of measuring almost any optically homogenous, translucent single-layer or small multilayer film within this range. Based on an advanced rotating compensator design, this system delivers optimal measurement performance on virtually all such film samples, even those deposited on silicon or glass substrates.


This budget-friendly ellipsometer is ideally suited for use in academic and R&D settings, particularly for investigating the thickness and uniformity of ultra-thin films (with 0.03 Å repeatability on native oxide).
