​This is a Schottky field emission gun instrument with an advanced monochromator with double Wien filters for high energy resolution EELS (20 meV measured on site). The next generation imaging filter (GIF Continuum HR) ensures high data-throughput and flexibility. The OneView camera can capture micrographs at 4k x 4k and the accompanying in-situ video software provides the possibility to record dynamic events at up to 300 fps.
The microscope is equipped with several detectors (HAADF, BF, SE, EELS, SAAF, dual EDX) enabling the collection of a wide range of data. The ultra-stable sample stage allows high-quality data collection over extended periods of time. 
The instrument can be booked here. For more information, please contact Research Engineer Stefan Gustafsson.
