In modern experimental physics the pinhole camera is used when the creation of a focusing element (lens) is difficult. We have experimentally realized a method of image construction in atom optics, based on the idea of an optical pinhole camera. With the use of an atom pinhole camera we have built an array of identical arbitrary-shaped atomic nanostructures with the minimum size of an individual nanostructure element down to 30 nm on an Si surface. The possibility of 30 nm lithography by means of atoms, molecules and clusters has been shown.

The prototype of a cathodoluminescent bulb with a field emission cathode based on carbon fiber is manufactured. The bulb comprises a high-voltage built-in AC–DC converter of the electric line voltage and a standard E27 cap. The luminous flux of the bulb amounts to 250 lm (comparable to a 25 W incandescent bulb), and its luminous efficiency is 30–40 lm/W at the wall-plug power of 5.5 W.
