With Ultim® Extreme, low-energy performance and ultimate spatial resolution are provided for EDS in the SEM. By integrating Extreme electronics and windowless construction with optimized sensor design and geometry, up to 15x greater sensitivity is offered in comparison to a traditional large-area SDD.
- Materials characterization at sub-1 kV
- Integrate with immersion optics to obtain high-sensitivity data at up to 30 kV with no compromiseDetection and mapping of Li X-rays Operate at energies below 2 kV to deliver sub-10 nm spatial resolution in bulk samples
Ultim Extreme Silicon Drift Detector, a ground-breaking solution for ultra-high-resolution FEG-SEM applications, offers solutions beyond traditional micro- and nanoanalysis.
The Ultim Extreme, a windowless 100 mm2 version of Ultim, has been developed to improve spatial resolution and sensitivity. Using a radical geometry, it optimizes imaging and also EDS performance in ultra-high-resolution FEG-SEMs while operating at low kV and short working distance. Ultim Extreme can be used to achieve EDS resolution comparable to that of the SEM.
