Abstract: | The Hitachi H500 transmission electron microscope has been modified in order that both the top and side entry specimen stages may be fitted simultaneously. This made possible top entry multi-specimen operation up to a maximum magnification of × 100,000 and a resolution of 1.8 nm, combined with the normal side entry stage facilities of ±60° tilt, 0.45 nm resolution and × 400,000 magnification. |
