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.
All of these apertures are made by the world's most experienced manufacturer, who pioneered aperture manufacturing for the first commercial electron microscopes.

Listed disk apertures are usually available ex our stock. Unlisted disk apertures are available (within six weeks) on request, but for these a minimum order of 10 apertures applies. If you have a regular requirement for an unlisted aperture, please advise; we will consider adding this to our range.

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