In atomic physics, a ridged mirror (or ridged atomic mirror, or Fresnel diffraction mirror) is a kind of atomic mirror, designed for the specular reflection of neutral particles (atoms) coming at the grazing incidence angle, characterised in the following: in order to reduce the mean attraction of particles to the surface and increase the reflectivity, this surface has narrow ridges.

Famous quotes containing the word mirror:
“The creation of “strong-minded” women, so-called, is due to the individualism of men, to the modern selfish and speculative spirit which absorbs everything within itself and leaves women nothing but self-assertion for their protection and support.”
