SEM with EDS

Ultra high resolution scanning electron imaging coupled with material spectroscopy tools The ULTRA 55 represents the latest development in GEMINI technology. Based on the SUPRA 55, the ULTRA 55 now comprises a fully integrated Energy and angle selective Backscattered electron (EsB) detector. The ULTRA 55 offers ultra high resolution for both SE to image surface information and BSE to present compositional information. The new EsB detector features an integrated filtering grid to enhance image quality and requires no additional adjustments. The EsB detector is less sensitive for edge contrast and charging effects which enables precise imaging and measurement of boundaries, particles, and features. Combined with the large multi-port analytical chamber, the fully motorised 5-axes motorised eucentric stage and the GEMINI high current mode the ULTRA 55 also offers superb analytical capabilities.

General Features:-

  • Ultra high resolution imaging at low kV
  • Fully integrated EsB detector for compositional information
  • Low kV BSE imaging at short working distance: WD = 1mm
  • High efficiency In-lens SE detector for high contrast surface imaging
  • GEMINI technology with high efficiency In-lens detector for high contrast topographic imaging
  • Easy operation through Windows XP based SmartSEM control software
  • Local Charge Compensator in ULTRA PLUS for imaging of non-conductive specimen

SEM with MonoCL

Ultra high resolution scanning electron with monochromatic imaging spectroscopy tools

General Features:-

  • Panchromatic and monochromatic imaging with high spatial and spectral resolution
  • Point and click selection of spectroscopy, imaging and mapping modes
  • Shortpass, longpass and bandpass imaging using filter options for increased flexibility

Multi-technique X-ray Photoelectron Spectroscopy with XPS-mapping capability

XPS tool for materials identification and analysis, and advanced studies AXIS ULTRA, a natural evolution from the AXIS 165, integrates the Kratos patented Magnetic Immersion Lens and Charge Neutralisation System with our new, patented Spherical Mirror Analyser. The Spherical Mirror Analyser provides real time chemical state and elemental imaging using the full range of pass energies and multi-point analysis from either real time or scanned images without the need for sample translation. A microchannel plate and phosphor detection system are incorporated into the system to provide a parallel imaging capability with high spatial resolution and high sensitivity. Advanced zoom optics enable a variable viewing area for the identification of macro or micro features. The instrument’s exceptional small spot capabilities (< 15 microns) are achieved via a combination of the magnetic lens and selected area apertures. The AXIS line of multi-technique photoelectron spectrometers provides scientists with unsurpassed performance for applications which require high energy resolution and high spatial resolution, high sensitivity, time efficiency and ease of use.

General Features:-

  • High Energy Resolution and Charge Neutralisation.
