Reverse side of 2.0x0.6mm aperture disc
NOTE

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%.

APERTURE STRIPS

A full range of molybdenum and platinum aperture strips, with various hole size combinations, is available for all electron microscopes.

These apertures are of excellent quality and well priced. All standard strip apertures are listed in our price link. Special strips with holes down to 5um, or strips with more than four holes, or in other metals are available on request. We don't stock aperture strips, but they are available within two to six weeks from ordering.
