Abstract
We have developed a particular combination of elements and devices which enables the portability of a scanning electron microscope (SEM). In particular the combination enables a small size, typically less than about 50 liters, a manageable weight, typically less than about 15 kg, and a low power requirement, typically less than about 100 W, which permits operation using power supplied from a portable source such as a battery. Higher performance versions may exhibit increased volume in the range of about 150 liters, increased weight, in the range of 45 kg, and a power requirement in the range of 300 W. The higher performance version of the portable scanning electron microscope may be portable with the assistance of a dolly (rolling cart) or with the assistance of attached wheels and pulling appendage.
