Both full size and benchtop Scanning Electron Microscope (SEM) systems from COXEM can be expanded to support Scanning Transmission Electron Microscopy (STEM) capabilities with the COXEM STEM Detector. This allows a COXEM SEM to handle multiple imaging applications outside of standard SEM imaging tasks.
COXEM's STEM Detector is mounted inside the SEM chamber, and can be retracted and tilted 90° out of the field of view to allow regular SEM functions. Support for the STEM Detector is fully integrated into the NanoStation operating software for COXEM SEMs, with the same simple and easy operation.
The COXEM STEM Detector is available as an option for all electron microscopes in COXEM's range, including the EM-30 Plus & LE Desktop SEM, the EM-30AX Plus & LE Desktop SEM with EDS, and CX-200 Plus Full-Size SEM.
True TEM Detector
Most STEM modules differ from the true TEM principle, and use a platinum mirror and the SEM's SE detector to collect an image. The COXEM STEM Detector uses a true TEM detector beneath the TEM sample.
The STEM Detector supports both Bright Field (BF) and Dark Field (DF) imaging.
TEM Grid Holder
A specially designed TEM grid holder is included with the STEM detector, which mounts onto the SEM stage. Up to 4 standard TEM grids can be accommodated in the holder. The holder has been designed to allow EDS analysis without the need for separate adjustment.
