Iliad 300 Scanning Transmission Electron Microscope

The new Iliad EELS Spectrometer and Energy Filter with advanced optics and high stability offers unique integration with TEM optics to improve the EELS data collection experience.

To optimize EELS experiments, a broad range of electron energies up to several thousand eV wide must be simultaneously transferred through the microscope and through the spectrometer, from specimen to detector, without introducing chromatic blur or chromatic distortions. To achieve this with other systems, the operator must continuously adjust both microscope and spectrometer settings to maintain the correct experimental conditions. The close integration between microscope electron optics and the spectrometer in the Iliad 300 (S)TEM matches chromatic defocus with the focus of the spectrum, helping to ensure accurate transfer for the entire range of experimental conditions.

An electrostatic beam blanker is used in electron microscopy to optimize the electron dose. It selectively blocks or blanks the beam, effectively turning it on and off over the specimen at a high frequency. TEMs typically use magnetic deflectors, which only have a response time in milliseconds and are not as reproducible as electrostatic deflectors. The Nanopulser enables precise temporal control over the electron dose delivered to the sample, giving it a wide range of applications ranging from dose-efficient imaging to time-resolved experiments.

Cutting-edge Thermo Scientific Velox Software for transmission electron microscopy offers comprehensive experimental control. It facilitates access to scanning transmission electron microscope (STEM and TEM) optics and detectors, enhancing reproducibility, yield, and support for quantitative STEM and TEM material analysis.

Velox Software stands out with its integrated ergonomic user interface and ease of use, providing ultimate quality in imaging and compositional mapping.
