[3dem] picture of SAD-aperture

[Philip Köck]

Hi.
  
  
Does anybody happen to have an SAD-aperture assembly (aka field limiting aperture assembly,
manual version) for a Jeol JEM2100F lying outside the microscope at the moment?


I would be really interested in a photo of it with some measurements,
mainly the diameter and length of the rod (the part that spans the distance between the surface and the
center of the column.


Alternatively, a sketch with dimensions would also be great.
  
  
All the best,
  
  
Philip
  
  
  PS: I'm trying to avoid opening up the microscope and getting drawings from Jeol is a lengthy procedure.
