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.
