The article presents the basic physical phenomena that affect the surface and the surface layer of the optical and technical glass when exposed to low-energy (E ≤ 10 keV) electron flux. We identified three stages in heat influence and two stages in electric influence of the electron beam on the optical material. The description of the physical processes that occur at each identified stage is provided. There given the examples how the electron beam affects the optical glass of category K-8, and БК-10 and photographic plates. The scheme of the basic phenomena and mechanisms that accompany the transformation of the surface layer of the optical and technical glass under the thermoelectric effect of the electron beam is provided.
