Hysitron PI Envision SEM Picoindenter
Hysitron PI Envision SEM PicoIndenter
Hysitron PI Envision is a leading-edge nanomechanical testing instrument designed for in-situ operation in standard SEMs, FIB-SEMs, small-chamber SEMs, and even synchrotron beamlines. Its sub-nanometer displacement and sub-micronewton resolution make it suitable for analyzing materials from soft polymers to high strength metals and alloys. This modular platform is highly upgradeable, supporting a powerful suite of techniques, including nanoindentation, property mapping, and high-temperature testing up to 800°C. PI Envision delivers best-in-class versatility, precision, and value ideal for multi-user facilities and budget-conscious laboratories.
Affordable, Reliable, Upgradeable, and Easy to Use
Hysitron PI Envision is an easily upgradeable platform that offers a powerful suite of in-situ testing techniques. It is an indispensable, affordable, and reliable SEM accessory for nanomechanical and nanotribological testing.
PI Envision delivers:
- Intrinsic displacement control, intrinsic load control, and open loop nanomechanical testing for a wide range of materials
- Advanced upgrades for performing nanotribology, property mapping, and high-temperature testing to 800°C
- Encoded stage control and 78 kHz feedback rate for fast, repeatable results from indentation, compression, tension, or fatigue testing
Essential Ease-of-Use Features
PI Envision is designed to streamline your work, with:
- An encoded stage to ensure precise sample positioning
- Positioning travel of 12x12 mm to provide easy sample access
- No-stitch property mapping for >1 mm x >1 mm area
- Two sample mounts to reduce manual sample changes
Configure Your System
All PI Envision configurations deliver intrinsic displacement actuation and control with sub-nanometer resolution, feedback rate of 78 kHz, and data acquisition up to 39 kHz.
The base system supports up to 10 mN force and sub-nanometer to 5 µm displacement range, making it an excellent choice for routine indentation, compression, and tensile testing of low-hardness to medium-hardness materials.
An optional xR transducer extends the maximum load to 250 mN and displacement range up to 100 µm, making it ideal for high-hardness materials and nanotribology.
Additional testing capabilities:
Additional testing capabilities include:
- Push-to-Pull (PTP) Tensile Testing — Uniquely simplifies tensile testing of nanostructures such as nanotubes, nanofibers, nanowires, and thin films
- Electrical PTP Tensile Testing — Enhances PTP testing with integrated four-point electrical measurements to study electromechanical coupling
- Electrical Characterization — Monitors changes in electrical properties during mechanical deformation; applicable to piezoelectric and other functional materials
- nanoDynamic Testing — Applies oscillatory forces to continuously evaluate viscoelastic and fatigue properties at room and elevated temperatures
