Backscattered Electron Detector Standards


An electron microscope, when equipped with a Backscattered Electron Detector, has the capacity to produce images in which contrast is controlled by the differences in atomic numbers (Z) across the specimen. We currently have four reference specimens which are available for testing the atomic number contrast performance of backscattered electron detection systems.


Each of the reference specimens consists of two high purity elements that have an atomic number difference of 1. They are embedded side by side in a contrasting matrix and are available as a single mount or can be incorporated into a block of standards.


Atomic Number Contrast Reference Standard Aluminium / Silicon (atomic numbers 13/14) Available as: ANC1314 - 5mm diameter x 5mm Brass Tube


Atomic Number Contrast Reference Standard Nickel / Copper (atomic numbers 28/29) Available as: ANC2829 - 5mm diameter x 5mm Brass Tube


Atomic Number Contrast Reference Standard Palladium / Silver (atomic numbers 46/47) Available as: ANC4647 - 5mm diameter x 5mm Brass Tube


Atomic Number Contrast Reference Standard Platinum / Gold (atomic numbers 78/79) Available as: ANC7879 - 5mm diameter x 5mm Brass Tube
