Aperture strip for FEI Pre-lens FIB
Aperture strip for the FEI pre-lens FIB column, with custom hole sizes to suit your application needs.
The pre-lens FIB column was used on the earliest generation single beam FIB systems from FEI, including:
- FIB600 series
Aperture sizes increase over time due to ion sputtering. We recommend installing a new aperture strip when beam currents increase 10% above starting values.
