TEM grid holder on SEM pin stub

This TEM grid holder holds up to 4 TEM grids. It enables imaging and analysing 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 ø2.1mm. 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, standard 3.2mm pin with a 15mm long pin. The longer pin allows for a larger distance from the SEM stage pin holder and therefore greatly reduces electron and X-ray scattering contribution for the SEM stage. TEM grid locations are numbered. Material: vacuum grade aluminium with brass screw.

Also available in copper for cryo applications
