Gatan Inc., Pleasanton, Calif. – a leading manufacturer of instrumentation and software used to enhance the performance of electron microscopes – and Dectris Ltd., Baden-Daettwil, Switzerland, – industry leader in hybrid-pixel X-ray and electron detectors for science and industry – announced the signing of a joint sales and service agreement pertaining to the use of Dectris technology in Gatan’s new Stela camera.
Gatan fully integrated a Dectris hybrid-pixel electron detector within the Gatan Microscopy Suite platform and now offers a complete workflow for advanced four-dimensional scanning transmission electron microscopy (4D STEM) diffraction. Known as the Stela camera, it will enable the mainstream adoption of the 4D STEM diffraction technique in electron microscopy labs around the world.
Hybrid-pixel electron detectors by Dectris bring countless opportunities for materials science TEM and STEM applications, such as 4D STEM, from increased instrument throughput to reduced total cumulative electron dose. With this new camera, researchers can have complete, efficient workflows to perform advanced, high-speed, and high-quality 4D STEM diffraction studies.
During the design and discovery of materials, researchers frequently use STEM to focus an electron probe (from a few nanometers to subatomic dimensions) onto the specimen to collect signals as the electrons interact with and scatter from the sample. 4D STEM diffraction is an advanced technique in which the probe is rastered on the specimen in a two-dimensional (2D) array. At each probe position, a 2D diffraction pattern is imaged on a pixelated detector, thus generating a 4D data cube that can be further analyzed.
A successful 4D STEM experiment primarily relies on robust and easy-to-use software for data acquisition and analysis, as well as high data quality and acquisition speed that is mainly dictated by the detector used to collect the diffraction patterns. This collaboration between Gatan and Dectris will bring these aspects together in a single package that enables researchers at all levels to access this critical experimental method.
