Platinum Aperture 3mm dia x 0.1mm, Hole 70um.
Platinum/iridium. High quality disc apertures for use in electron microscopes, Focus Ion Beam, microprobe and X-ray
Platinum/Iridium - 3.00mm dia, 0.1mm thick. High quality disc apertures for use in electron microscopes, Focus Ion Beam, microprobe and X-ray systems.
We have a wide range of high-quality disc apertures for use in electron microscopy systems. These apertures are manufactured to tight tolerances with precision drilled holes and are made from a platinum/iridium alloy 95:5%. 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.
