Backscattered Electron and X-ray ​(BEX)

What is BEX?

BEX is a pioneering analytical technique for SEM. BEX combines Backscattered Electron and X-ray (BEX) imaging in a single technique, simultaneously. In an industry breakthrough, the best of both techniques are integrated to accelerate your time to discovery.

What can I do with BEX that I couldn’t before?​

Until now, analysis in an SEM has been a static, step-by-step process that relied on experience-based instinct to obtain good results in a timely manner. A secondary electron signal obtains topographical information about a sample. Backscattered electron signal provides indicative compositional information. These data combine to give the typical black and white electron microscope image. To obtain firm compositional information, EDS analysis is then applied. If nothing of interest is found in the area of sample under scrutiny, you have to start over.​

With BEX imaging
With traditional imaging

BEX combines the topographic, crystallographic, atomic number and elemental information in an immediate visual output while you navigate around your sample. So you no longer need to trust luck or judgement to find areas of interest in your sample. Instead, BEX allows you to immediately review the results, and either focus in on points of interest or move on. ​

Unity BEX Imaging Detector​

Why it is setting the imaging standard​?

The Unity BEX imaging detector delivers rapid high-resolution colour images embedded with elemental data and supported by the rigour and accuracy you expect from our leading technology. It’s revolutionary design, with both backscattered electron and X-ray sensors directly below the pole piece, is not only what enables Unity to combine backscattered electron and X-ray imaging, simultaneously, creating the BEX imaging technique. This unique positioning means there are no shadows and results in a superior quality of image.​

Best imaging, best throughput​

Not only does the Unity imaging detector set a new standard for the quality of imaging available today. In tests, the Unity detector has boosted microscope productivity by up to 100x. Regardless of the nature of your research or analysis, Unity enables a significantly greater throughput, helping maximise the value of your investment in your instrumentation. And, because an existing microscope can be upgraded with a BEX imaging system, you can boost your productivity and flexibility and extend the life of your current devices.​
