high-power magnification

Under high-power magnification, a glass tool (holding pipet) is used to hold an egg in place.

These capabilities, combined with that of high-power magnification that was also inherent in the method, yielded possibilities not even remotely approached by anything else on the market.

Then they used a scanning electron microscope to give high-power magnification of the scratches for study, and conducted a three-dimensional statistical analysis of the direction of the scratches.
