Aperture strip for FEI Magnum FIB column, custom configuration per user requirements to allow a customized set of beam currents for the way you use your FIB.
Define up to 12 different beam currents, or select up to 10 beam currents with multiple apertures of the same current.
Choose from 20nA, 13nA, 10nA, 7nA, 5nA, 3nA, 1nA, 500pA, 300pA, 100pA, 50pA, 30pA, 10pA and 1pA.
Aperture sizes increase over time due to ion sputtering. We recommend installing a new aperture strip when beam currents increase 10% above starting values.
