Nanocone-Textured Glass Surface Microscope Image (IMAGE) DOE/Brookhaven National Laboratory Caption This cross-sectional image from a scanning electron microscope shows a glass surface textured with 170-nanometer-tall cones. The cones are packed very close to each other, only 52 nanometers apart. A two-inch piece of glass has 900 billion cones on its surface.
