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 |
AVA strip aperture sizes increase with use due to ion sputtering. We recommend a new strip be installed when beam currents are an average of 10% greater than these values.
