Silicon Drift Detectors (SDD) for X-ray Fluorescence (XRF)


RaySpec XRF X-Ray Fluorescence Silicon Drift Detectors are available with a comprehensive choice of sensor active area, tube length and collimation, and with vacuum compatibility, to ensure the right detector is always available for the job.

Designs are customisable to suit individual instruments and provide consistency of spectral qualities over extremes of count rate and temperature.

Compact XRF Detector

The compact profiles allow easy integration into OEM X-ray fluorescence instruments from large laboratory systems to the smallest bench top models. Detector outputs are customisable ensuring that XRF detectors are compatible with all modern pulse processing systems.

Detectors are available with the latest low-capacitance ASIC primary amplification stage which enables the detector to generate improved resolution at very short peaking times and hence ultra-high count rates (up to several Mcps, processor dependent).

The RaySpec XRF detector range provides compact detector designs for OEM X-ray fluorescence Detector applications with the following features:

Large Area XRF Detector


  • Wide range of active areas and performance (10-170mm²)
  • Excellent resolutions
  • Optimal thermal design and control for performance stability
  • Fully compatible with all digital pulse processors
  • Air/Vacuum/He flush compatible
  • Custom interface adaption
  • Cost effective design
  • Low fluorescence collimation
  • Customised designs


RaySpec also offers the DX200 Digital Pulse Processor, which provides excellent overall system performance when paired with a RaySpec XRF detector. The DX200 is USB controlled with spectrum transfer available via USB or real time event by event data presented directly at a 20-way parallel port. The DX200 utilises a fast 16bit 40Mhz ADC and has fast recognition circuits for excellent pile-up rejection. It is bundled with Control and Data transfer software.
