STEM Systems in SEM
Equip your SEM with PNDetector’s STEM System
Advanced new SEMs make STEM also in SEM more and more popular.
PNDetector’s STEM Systems are based on our Advanced STEM Detectors – adding all the electrical and mechanical components to provide an easy and user friendly installation in your SEM. Different configurations of main amplifiers for fast signal processing are availableas well as the retraction mechanism to provide safe and exact movement of the detector into your chamber when needed.
Key Features
-
Our detector systems comprise the full variety of our STEM Detectors dedicated for SEM, with typically four channels for BF, ADF, LAADF and HAADF.
-
The STEM signals are processed by our low noise and fast-amplify electronics.
-
The retractable arm works highly precisely with excellent position repeatability.
