Aperture strip for FEI Pre-lens FIB column
| SKU: | 100038 |
Automatic Variable Aperture (AVA) strip for FEI Pre-lens FIB column, standard configuration for 10 different beam currents. The aperture sizes provide beam currents of:
| 1pA | 4pA | 11pA | 70pA | 150pA |
| 350pA | 1nA | 2.7nA | 6.6nA | 11nA |
The pre-lens FIB column was used on the earliest generation single beam FIB systems from FEI, including:
- FIB200
- FIB600 series
- FIB800
- FIB830
Aperture sizes increase over time due to ion sputtering. We recommend installing a new aperture strip when beam currents increase 10% above starting values.
