To test for centration, a lens is placed into a cup upon which pressure is applied.
Relationship between Surface Sag Error and Optical Power of …
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. Periodicity and their spatial frequencies, rather than the surface topography profile, determine the optical performance.
