OnPoint

Backscattered electron (BSE) detector for SEM

The Gatan OnPoint is a backscattered electron detector for SEM (Scanning Electron Microscopes). Study non-conductive samples including polymers, plastics and biological materials. Optimised for low kV, for studying uncoated biological samples, low atomic number (Z) elements and large 3D datasets.

  • Resolve features distorted by charging or beam damage: Low kV to reduce charge build-up and protect delicate samples
  • Capture large, 3D datasets quickly: Up to 6 times faster for large field of view images and 3D.
  • Differentiate low-Z elements: Highest signal-to-noise ratio (SNR) available, to distinguish between elements with similar atomic numbers.
  • Highest BSE collection efficiency: Capture electrons that other detectors miss, with minimal noise.
  • Optimum performance within minutes: Maintain the best performance without the need for service visits, with user-exchangeable sensors.

  • Low noise

 

Faster BSE Detection

Four-Fold Faster Imaging: Compare image quality from the previous generation 3View (top) with the OnPoint (bottom) at various dwell times. The OnPoint detector takes equal or better quality images with shorter dwell times.
