Apreo 2 S LoVac

Apreo 2 S LoVac is a Schottky Field Emission Scanning Electron Microscope (FESEM) that combines high- and low-voltage ultra-high resolution capabilities with an electrostatic lens design together with a low vacuum mode for charge compensation on non-conductive material. The instrument features beam deceleration and unique in-lens detection offering unprecedented contrast and versatility to researchers working with a variety of materials and devices.

The key enabling technologies are all integrated onto a single platform and comprise:

  • Novel Field Emission Electron Optics optimized for both high current and high resolution meeting all imaging and analysis needs
  • Trinity detection system for fast imaging, and easy collection of all available signals
  • High-precision specimen goniometer with 110 mm travel along the x and y axes
  • A Windows 10, 4-view "Beam per View" User Interface with User Guidance
  • System architecture is optimized for automation, which is optionally available (e.g. MAPS™)

Features and specifications:

Vacuum

Apreo 2 S LoVac uses an entirely oil-free vacuum system, featuring:

  • 1x 240 l/s turbomolecular drag pump
  • 1x Scroll pumps
  • 2x Ion Getter Pumps
  • Integrated battery backup for IGPs on the electron column, a FEG safety mechanism (for recoverability after an unplanned power outage)
  • Auto bake-out and Auto-start enable fast and easy maintenance of the FEG source
  • Low vacuum mode up to 500 Pa for charge compensation of non-conductive samples
  • Seamless switching between high vacuum and low vacuum with an automated mechanism for attachment of a pressure limiting aperture to the pole piece

Sample Navigation

Apreo 2 S LoVac is standard equipped with a 5-axes motorized x-y-z-tilt-rotate stage, providing movements:

  • X and Y range: 110 mm (motorized); Z range: 65 mm (motorized)
  • Tilt: -15 to +90 degrees (motorized)
  • Eucentric tilt
  • A unique standard specimen holder with labeled positions and unique stage mounting, allowing simultaneous loading of 18 standard samples (varnothing 12 mm), three 45circ pre-tilted samples, two row bars (one in horizontal and one in 52circ pre-tilted position), and a spring-loaded clamp holder for mounting cross-sections.

A selection of additional sample holder kits is optionally available (including stub holders, additional TEM sample holders and vise specimen holders).

Joystick stage control is available as an option.
