Aperture strip for FEI Magnum FIB column
| SKU: | 100044 |
Automatic Variable Aperture (AVA) strip for FEI Magnum FIB column, standard configuration for 12 different beam currents. Aperture sizes provide beam currents of:
| 1pA | 50pA | 500pA | 5nA |
| 10pA | 100pA | 1nA | 7nA |
| 30pA | 300pA | 3nA | 20nA |
Aperture sizes increase over time due to ion sputtering. We recommend installing a new aperture strip when beam currents increase 10% above starting values.
