Thermo Fisher Scientific’s Thermo Scientific EMPAD G2 detector is designed to help researchers see and understand materials in unprecedented detail.
EMPAD G2 enables high-speed four-dimensional scanning transmission electron microscopy (4D STEM), an advanced form of electron microscopy that captures far more information about a material than a standard image, helping researchers better understand its structure and properties.
Capturing weaker signals alongside stronger ones can help researchers measure characteristics, including a material’s structure, chemistry, strain and electric and magnetic properties in a single experiment. EMPAD G2 supports advanced applications, ranging from strain mapping and differential phase contrast (DPC) to multi-slice electron ptychography for three-dimensional characterization at the atomic scale.
As 4D STEM becomes more widely used in academic and industrial research, detector performance is increasingly important. Researchers need to capture large amounts of information quickly while accurately measuring signals that can range from extremely strong to extremely weak. EMPAD G2 is designed specifically to meet these demands and help researchers get reliable quantitative information from a single acquisition.
EMPAD G2 is also fully integrated with the user-friendly Thermo Scientific Velox software. Researchers can collect and analyze multiple types of data, including simultaneous 4D STEM and energy-dispersive x-ray spectroscopy (EDS) within a single workflow. This integration helps simplify advanced materials analysis and supports more reliable, repeatable results.
