High Resolution, High Precision, and High Magnification
High resolution, high precision, and high magnification are an absolute must in today’s failure analysis industry. Sage Analytical Laboratories is capable of taking breathtaking images of samples with our Field Emission Scanning Electron Microscopes (FE-SEM).
With the increased electron beam current supplied by our electron source, we are able to obtain high resolution and accuracy Energy-Dispersive X-ray Spectroscopy (EDS) results.
Combine this with the multiple imaging modes, 5-axis stage control, digital image processing, multiple detectors, and in-situ FIB capabilities; it quickly becomes apparent this is a world-class system. Multiple vacuum settings guarantee charge free imaging of even non-conducting samples.
The specifications from the FEI Quanta website show how versatile a system like this is:
