astigmatism (optical systems) - wikipedia

An optical system with astigmatism is one where rays that propagate in two perpendicular planes have different foci.If an optical system with astigmatism is used to form an image of a cross, the vertical and horizontal lines will be in sharp focus at two different distances.The term comes from the Greek - (a-) meaning "without" and (stigma), "a mark, spot, puncture"

optical glass fabrication technology. 1: fine grinding

The mechanism for fine grinding using diamond tools is shown to depend on the properties of the glass, the acidity of the grinding fluid, as well as the chemical and mechanical properties of the abrasive bonding material. Knowledge of the mechanism is essential for the implementation of this technology for the deterministic fabrication of precision optical surfaces
