高级背散射探测器
The innovation- the ultrafast PNDetector’s Advanced BSD Module
We integrated professionally the preamplifier into the same ultraslim housing as the Standard BSD detector to optimize your speed of operation and the ease of workflow.
Key Features
-
Ultrafast imaging at HD TV-speed with pixel dwell times down to 10 ns is possible
-
Sharp images without smearing artifacts
-
Direct sample search at highest scan speeds
-
Enhanced depth of information due to the broad energy range down to 0.5 keV
-
Customer specific solutions to perfectly fit any SEM system
-
Vacuum compatible components
-
Available in two versions of single and double switchable preamplification gains
