Aperture Strip for FEI Sidewinder / Tomahawk FIB

Request Quote

A direct replacement for FEI 4035 27X XXXXX.

Automatic Aperture Mechanism (AAM) strip for FEI Sidewinder and Tomahawk FIB columns, standard configuration for 15 different beam currents.

Aperture sizes provide beam currents of:

1.5pA 50pA 500pA 7nA
10pA 100pA, 2 ea. 1nA 10nA
30pA, 2 ea. 300pA 3nA, 2 ea. MAX

Please note the MAX beam current available is typically 20nA or about 60nA, which depends on the configuration of the extractor assembly installed (not the aperture strip).  So, if your Sidewinder column is currently limited to 20nA but want to upgrade to 60nA, just let us know you need the 60nA extractor assembly – it’s that easy to triple the available beam current and milling throughput of your system!
