Bruker Hysitron PI 85L

Compact in-situ nanomechanical test system for SEM

The PI 85L SEM PicoIndenter is a depth-sensing nanomechanical test instrument for Scanning Electron Microscopes (SEM). Perform quantitative nanomechanical testing while simultaneously imaging with your SEM. Coupling these techniques also enables extremely accurate probe positioning.

  • Nanoindentation, compression, tension and bending test modes
  • In-situ data displayed beside SEM imaging for a complete picture of your sample’s behaviour
  • Compact design for small chamber SEMs, Raman, beamlines and optical microscopes
  • Optional upgrades for extra capabilities, including heating and electrical characterisation

Technical Details

The PI 85L SEM PicoIndenter is the latest generation of Hysitron’s in-situ nanomechanical testing system. It was originally designed for SEM but the low profile is also suitable for Raman, optical microscopes, beamlines and more.

  • Extremely fast 78kHz control system
  • Accommodates samples up to 10 mm thick
  • Precise sample positioning with >3 mm in all three directions (XYZ)
  • Mechanically coupled sample stage and transducer for rigid stability
  • Designed for maximum stage tilt and minimum working distance, for the best imaging set-up
  • Active vibration dampening, with proprietary Q-Control technology
  • Transducer technology with electrostatic actuation and capacitive displacement sensing
