FilmTek 3000 SE

The FilmTek™ 3000 SE high-performance benchtop ellipsometer/reflection-transmission spectrophotometer provides a versatile single-instrument solution for investigating very thin absorbing films on transparent substrates.  

 

This system combines our rotating compensator-based spectroscopic ellipsometer design with high-performance DUV multi-angle reflectometry and transmission measurement capabilities. It is consequently able to simultaneously and independently measure the thickness, refractive index, and extinction coefficient of very thin absorbing film samples on transparent substrates, as well as virtually any other transparent film sample <1 Å to 150 µm thick, with very high accuracy and repeatability.

 

The FilmTek 3000 SE's fully integrated configuration includes complete automation and advanced material modeling capabilities, allowing users to collect reflection, transmission, and ellipsometric data with exceptional ease and efficiency. Moreover, this system can be optionally configured to collect polarimetry data, making it more broadly applicable to use-cases requiring birefringence measurement (e.g., optical coating analysis). Its multimodal, easy-to-use, extendable design makes FilmTek 3000 SE ideal for academic- and R&D-level applications.
