Carl Zeiss AG - Supra 25

Year of introduction
Status historical ( out of sale )
Company Carl Zeiss AG
Categories Microscopy: Electron: SEM: FE
This truly flexible entry level SUPRA™ 25 FESEM with a versatile analytical specimen chamber can be easily expanded with a choice of optional detectors and a full range of accessories. Utilising the unique GEMINI® field emission column it delivers superb resolution over the complete high voltage range. The large 5-axes motorised cartesian stage is particularly useful for handling a number of smaller specimens simultaneously. It is equally useful for accommodating bulky or irregular shaped specimens.

Key Features
  • Ultra high resolution over the full high voltage range
  • Minimal adjustments required over the full operating voltage range
  • High probe current for fast X-ray analysis and mapping
  • High efficiency In-lens SE detector for clear surface specific imaging
  • Short analytical working distance of 8.5 mm for simultaneous high resolution imaging and X-ray analysis
  • Easy operation through Windows® XP based SmartSEM™ control software
