The Sigma HD VP SEM, from Zeiss, is a variable pressure field emission scanning electron microscope. The instrument combines high resolution imaging with the capability to perform advanced analytics while maintaining flexibility and ease-of-use.
- Magnification: x12-1M
- Acceleration Voltage: 0.1-30kV
- Probe current: 3pA-40nA
- 5 Axis Motorized Stage: X=125 mm, Y=125 mm
Detectors
- Everhart Thornley Secondary Electron Detector
- Inlens Secondary Electron Detector
- Inlens Energy Selective Backscatteres Electron Detector (EsB)
Imaging Modes
- High Vacuum (HV) mode – standard mode for analyzing conductive specimens.
- Variable Presurre (VP) mode – beneficial for imaging non-conductive specimens without additional specimen preparation. The partial pressure in the chamber is between 5 – 30Pa.
