In optics and especially telescope making, sagitta or sag is a measure of the glass removed to yield an optical curve. It is approximated by the formula $${\displaystyle S(r)\approx {\frac {r^{2}}{2\times R}}}$$,where R is the radius of curvature of the optical surface. The sag S(r) is the displacement along the optic … See more Optical surfaces with non-spherical profiles, such as the surfaces of aspheric lenses, are typically designed such that their sag is described by the equation Here, See more • Versine • Chord See more WebDiffractive optical elements (DOEs) are optical components that deflect light into multiple orders at precise angles.
