The MAG*I*CAL performs all major TEM calibrations: All TEM magnification ranges, Camera constant, Image Diffraction Pattern Rotation, Directly traceable to a natural constant. Magnification range from 1,000x to 1,000,000x.
Shadowcast carbon replicas of diffraction parallel line gratings with spacing of 462.9nm, 2160 lines per millimeter onto 3.05mm grid.The same ruling 2160 lines/mm, cross at 90° to one another give additional accuracy to magnification checks and aid in checking distortion.
Since crystal lattice plane spacings are accurately known from x-ray measurements, they provide a good test of microscope stability and a calibration of magnification in the upper range of magnification of the instrument.

Evaporated Pt/Ir on Holey carbon film. Holey carbon film support provides holes for ease of focus and astigmatism correction. The dots of evaporated Pt/Ir provide dense particles for resolution checks through the particle seperation test.
