Robinson™ Backscattered Electron (BSE) Detector for Scanning Electron Microscopes

Signal Mixing Module for mixing composite images of secondary electrons and backscattered electrons.




Introduction:
Generally speaking, a backscattered electron (BSE) image contains compositional information and very little topographical information. And without the topographical information, it is often times difficult to properly interpret the BSE image results. The beauty of the signal mixing module is that one can "mix" the two signals, both secondary electron (e. g. the normal SEM image) with the BSE image and it can be done in any combination of addition or subtraction in order to get the optimum end result.

Actual use:
What this really means is that one can start out with a 100% BSE image and start adding to it incremental amounts of secondary electron intensity, down to 75% BSE, and then 50% , etc. all the way down to 0% BSE and 100% secondary electron image.
