Introducing the Octane Elite Silicon Drift Detector (SDD) Series

EDAX Octane Elite Silicon Drift Detector (SDD)

The game changing advancements in the Octane Elite Silicon Drift Detector (SDD) Series take detector technology to the next level. This line of detectors incorporates a new silicon nitride (Si3N4) window, which offers remarkable improvements in low energy sensitivity for light element detection and low kV microanalysis. The Octane Elite Series also uses the widely praised CUBE technology, which yields high speed X-ray data processing within a smaller and fully vacuum encapsulated detector device.


Best light element performance

The transmission improvements of the silicon nitride window can be as much as 35% compared to a polymer window, leading to greatly improved light element performance and significantly more critical data for the materials analyst.

The results to the right show spectra acquired from a silicon dioxide sample at 10 kV. The two spectra have been scaled to the same peak amplitude at the Si K peak to facilitate comparison and a clear improvement for the Si3N4 window is seen in the increased oxygen peak intensity.

The clear improvement for the Silicon Nitride window is seen in the increased oxygen peak intensity.

Low kV performance

The mechanical properties of Si3N4 allow the windows to be very thinly fabricated, offering a great benefit in terms of sensitivity, enabling optimal low voltage analysis.


The material properties and durability of Si3N4 ensure the most robust and reliable detectors available for all EDS applications.

Features and Benefits

Si3N4 window
  • Thermal resistance enables in-situ testing and analysis
  • Corrosion and shock resistance
  • Higher sensitivity for superior low kV performance
  • Unique grid arrangement blocks fewer X-rays
