Optics sag
WebBeginning from the surface expressions of progressive addition lenses, the relationship equations between the surface sag and optical power distribution are derived. They are demonstrated through tolerance analysis and test of an example progressive addition lens with addition of 2.09D (5.46D-7.55D). The example addition surface is fabricated ...

Webairspace is dependent on the primary parameters of spacer thickness, contact diameter, sag, and radii. Figure 2 – Figure from (Magarill, 1999). Airspace is dependent on sag (A), spacer thickness (B), contact diameter (C), and radii (R). The following parameters are what Magarill defines as primary and can be used to tolerance an optical system. 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

WebAstigmatism (optical systems) 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 α- ( a ...
