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. Aperture flamer also available.

Materials: Gold (Au), Platinum (Pt or Pr/Ir), Molybdenum (Mo), Tantalum (Ta), Silicon (Si).

Note: Platinum apertures are made of platinum/iridium 95/5%.
