Also described as the Final Lens Strip Aperture, this product is produced with the same plasma-FIB technology found in our HyperFIB Upgrade system to yield a set of precision micro-machined apertures, guaranteed to deliver the same quality beam as you ۪ve experienced for the life of your system.
Unlike the original OEM product which has a thin Mo film on a Si substrate, our SEM aperture strip is made of pure Molybdenum thus avoiding flaking of a Mo film which will affect image resolution and lifetime of the strip. We recommend installing a new SEM aperture strip assembly yearly, and on each installation of a new electron source for best performance.
This strip is configured with two 30um apertures on each side of a centrally placed 50um aperture, plus a larger diameter aperture for initial beam alignment. Need different sized apertures? We excel at providing customized aperture configurations for your SEM and FIB - just Contact Us and describe what you need!
Our SEM aperture strip assembly is applicable on FEI several product lines including:
