PELCO® STEM Imaging Holder

Interchangeable
Modular SEM Specimen Holders

This extensive line of specimen holders all have a female M4 thread and are compatible with all of our modular SEM Stage Adapters. If used with the Jeol or ZEISS/LEO dovetail stage adapter one of the adapter buttons 15372 or 15372-10 is needed.

PELCO® STEM Imaging Holder, M4

The PELCO® STEM imaging holder enables STEM imaging in the SEM by using the standard Everhart-Thornley SE detector in the SEM chamber. The standard 3mm TEM grid is placed in the grid holder and located under the scanning beam. The STEM image is created by the adjustable Pt conversion plate which must face the chamber SE-detector. Cost-effective method for STEM imaging by using the existing SE detector in the SEM chamber. The included anti-scatter sleeve, placed between the holder and the SEM pole piece, contains secondary electron from the sample surface and prevents these from being detected; the result is clear STEM imaging. Overall height with anti-scatter sleeve is 37.5mm (1-1/2") and 29.2 (1.15") without the anti-scatter sleeve. Material: vacuum grade aluminum, brass grid holder, platinum conversion plate and conductive plastic.
