Standard STEM Detectors
Get the best STEM images with PNDetector's Standard STEM Detectors
The detectors are available in different chip segmentations and ring structures. They can be used in TEM as well as SEM. On request custom segmentation can be applied.
Key Features
-
Standard STEM Detectors are the best solution for fixed mounted configurations with a minimum of space available.
-
All our STEM Detectors are available in this configuration, varying from 10 to 22 mm diameter, 1 to 3 rings, 4 to 13 channels, equipped with a central hole or a bright field
-
A separate preamplifier supporting up to 13 channels improves your SNR.
