  • Application-Specific Modes include: Bright- and dark-field imaging; TEM microprobe and nanoprobe analysis; small-probe convergent beam; large specimen tilt compatible with high resolution; and, conical dark-field imaging.
  • LaB6 gun.
  • Accelerating voltage range of 20 to 120 kV.
  • Magnifications up to 700,000x.
  • Point-point resolution: 0.34 nm; Line resolution: 0.2 nm.
  • Specimen holders: Double tilt; single tilt; tilt-rotate; single and double tilt cooling; single and double tilt heating; straining holder; and, low background single tilt EDX.
  • Energy Dispersive X-ray Spectrometer: EDAX PV9900 with an ultrathin window allowing signal from boron to uranium.

Sample applications include:
