Quality Control Test Standard C consists of:
1. Standards: Hole to accept a 25mm or 32mm Ø x 5mm Reference Standard
2. Duplex Brass: Used for checking the contrast efficiency of Back Scattered detectors and it is capable of detecting two major copper/zinc phases of 0.1 atomic number difference.
3. Faraday Cage: A Faraday cage is used for measuring the current of the beam at the specimen plane. The beam of electrons is focused inside the hole by increasing the magnification so that when the hole fills the screen all the electrons are trapped and a true measure of current is achieved. The Hole size in FC “aperture” - 150 microns.
4. BSE Atomic No. Reference: Choose from: Al/Si, Nu/Cu, Pd/Ag or Pt/Au
5. Resolution Standard (Medium): Gold crystals 5-150nm on a carbon background which is useful for checking the performance of the SEM under high-resolution conditions i.e. finer than a 10 micron probe.
6. Resolution Standard (High): Gold crystals <3-50nm on a carbon background which is useful for checking the performance of the SEM under high-resolution conditions i.e. finer than a 10 micron probe.
7. Silicon Magnification Grid: Silicon test specimen with a pitch of 10 µm and lines at 10 and 100µm. Useful for calibration and image distortion checks in the 100x to 1000x magnification range.
