Amptek - Beryllium Free X-Ray Windows Detector

• Comparable transmission efficiency to Be foils over a wide energy range, typical to hand-held and benchtop XRF applications
  • Results from an instrument will not be greatly affected when switching from Beryllium to B4C windows.
  • Can be used in most places where a beryllium window was previously used. 
• Non-toxic material provides worry-free handling during installation and use
  • Concerns over the potential health hazards of beryllium and exposure are not an issue with these windows. 
• Less thickness variation as compared to typical Be foils
  • The beryllium window forming process allows a fair amount of variation in window thickness.  The tightly controlled semiconductor fabrication process on the B4C windows produces a much more consistent window thickness.  
  • OEM`s prefer this as they can expect similar transmission from detector to detector, even at lower energies.  
  • Allows for better modeling in quantitative calculations if the window thickness more closely matches the nominal values.

B4C windows have been designed to provide transmissions comparable to standard ? mil and ½ mil Be windows.  The initial product release utilizes a uniform 3.5 µm thick B4C layer, self-supported, without the need for an underlying grid.  An aluminum outer coating provides a grounded surface to help shield the detector from EMI.
