TEM Grid Holder on 25mm Stub

This TEM grid holder holds up to 4 TEM grids. It enables imaging and analyzing specimens on TEM grids in the SEM.

For EDS applications it is beneficial to place thin films on a TEM grid or small particles on a TEM grid with a support film.
This can significantly reduce background in the EDS spectrum and increase detection limits of the EDS detector.

Hole size in the top and base is 2.1mm. Opening angle on the holes in the top and base is 120 to reduce electron scattering and improve X-ray collection.
Overall diameter is 18mm (0.7″), overall height is approximately 25mm (1″) with a stand-off pin mounted on a 25 x 10mm JEOL mount.

The stand-off pin minimizes electron and X-ray scattering contribution from the stage.
TEM grid locations are numbered. Material: vacuum grade aluminum with brass screw.
