Aperture strip for FEI Tomahawk / Sidewinder FIB column, custom configured for up to 15 different beam currents.
Many customers request a non-standard set of apertures / beam currents, and we’re happy to oblige. Often we find a standard aperture configuration leaves several apertures essentially unused, while other apertures receive the majority of beam time and are quickly enlarged, ending with a costly but underutilized configuration.
Select up to 15 aperture sizes with beam currents ranging from 1.5pA to the maximum current allowed with your column.
Typical beam currents to chose from include:
Please note the MAX beam current available is typically 20nA or about 60nA, which depends on the configuration of the extractor assembly installed (not the aperture strip) in your column. So, if your Sidewinder column is currently limited to 20nA but want to upgrade to 60nA, just let us know you need the 60nA extractor assembly – it’s that easy to triple the available beam current and milling throughput of your system!
Importantly, unlike the system OEM, we quickly design and productize your custom design, making it available for simple re-ordering.
