The 4th generation Film Sense Multi-Wavelength Ellipsometer systems are now available! The primary improvements in this generation are the additional wavelengths and spectral range for the FS-8 model, which further enhance the measurement capabilities over a wide range of thin film applications. The new systems offer the same benefits of the patented* Film Sense ellipsometer technology (long life LED light sources, fast and reliable no moving parts detector, compact design, and web browser software interface), while maintaining ease of use and affordability.
