No single component of an X-ray microanalysis system is as critical to performance and accuracy as the X-ray detector. For more than thirty five years Thermo Fisher Scientific has pioneered the development and manufacture of high-resolution X-ray detection solutions for electron microscopy. We offer a range of X-ray detector options to fit your specific sampling needs.
Thermo Fisher Scientific provides detectors for all currently available electron column instruments with custom-designed mechanical interfaces to assure vacuum integrity and optimum collection efficiency. Unlike manufacturers that adapt a few designs to fit a specific column, Thermo Fisher Scientific has detector designs to correctly interface to any SEM, LVSEM, FESEM, TEM, STEM, Probe, DRT, Dual Column FIB or Auger.
Combined with next generation X-ray microanalysis systems for traditional EDS and Spectral Imaging-based analysis, we provide complete high-resolution, high-throughput solutions, from routine analysis to advanced research applications.

UltraDry Silicon Drift Detector
• UltraDry 30 - 30 mm2 active area for high throughput, less sample damage
• UltraDry 10 - 10 mm2 active area and the ultimate in peak resolution
• Resolution options from 128eV to 143eV
• Light element detection down to Beryllium on selected models
• Guaranteed performance on the electron microscope
• Electrically cooled with no fans or external cooling source. No LN operation eliminates the hazards, inconvenience, and costs associated with tradition liquid nitrogen cooled detectors.
• Compatible with most SEM, FESEM and Microprobes

NanoTrace LN-Cooled Si(Li) Detector
