Profile B, Platinum Aperture 2mm dia x 0.6mm Hole 10um

We can supply a wide range of high quality disc apertures for use in electron microscopes, Focus Ion Beam, microprobe and X-ray systems. These apertures are manufactured to tight tolerances with precision drilled holes. They are usually made from a platinum/iridium alloy 95:5% or molybdenum, although tantalum can be supplied for some applications. Platinum apertures can be made with hole sizes down to 5µm diameter whereas the smallest size for molybdenum is 10µm. The apertures can also be used for non-electron microscopy applications where precision small holes are required for light optics, gas and liquid flow purposes.
