EM Apertures
ProSciTech retains a large stock of apertures for electron microscopes. Except for apertures made from very thin materials, platinum and molybdenum apertures are counter-bored to minimise the aperture passage and hence contamination rates.
Apertures are made by the world's most experienced manufacturer, who pioneered aperture manufacturing for the first commercial electron microscopes.
Materials: Gold (Au), Platinum (Pt or Pr/Ir), Molybdenum (Mo), Tantalum (Ta).
Note: Platinum apertures are made of platinum/iridium 95/5%.
