VEGA3 SB

A fully PC controlled SEM with conventional tungsten heated cathode intended both for high vacuum as well as for low vacuum operations. Outstanding optical properties, flicker-free digital image with super clarity, sophisticated user-friendly software for microscope control and image capturing using Windows™ platform, standard formats of stored images, easy image management, processing and measurements, automatic setup of the microscope and many other automated operations are among the characteristic features of the equipment.

 

Analytical Potential

  • The SB chamber is equipped with a 3-axis motorized stage
  • First-class YAG scintillator-based detectors
  • 10 chamber interface ports with optimized analytical geometry for e.g. EDX, EBSD, EBIC
  • Selection of optional detectors and accessories
  • Full operating vacuum can be reached within a few minutes with powerful turbomolecular and rotary fore vacuum pumps.
  • Investigation of non-conductive samples in the variable pressure mode (SBU) version
  • 3D measurements on a reconstructed surface utilizing 3D metrology software

VEGA3 Configurations

VEGA3 SBH
A high vacuum model of SEM with 3-axis motorized stage for investigation of small conductive samples.

VEGA3 SBU
A variable pressure SEM that supplements all the advantages of the high vacuum model with the extended facility for low-vacuum operations, enabling the investigation of non-conductive specimens in their natural uncoated state.

VEGA3 SB - EasyProbe
The EasyProbe is a favorable package of a scanning electron microscope fully integrated with a selected EDX microanalyser. EasyProbe is available in both high vacuum and variable pressure variants. The system is delivered with a touch screen.
