A Laguerre-Gaussian beam is an optical vortex with a line singularity along the beam axis. An optical singularity is a zero of an optical field. The phase in the field circulates around these points of zero intensity (giving rise to the name vortex). Vortices are points in 2D fields and lines in 3D fields (as they have codimension two).
S2=vertex of the second optical surface; SH=distance from the vertex of the first optical surface to the primary principal plane; S′H′=distance from the vertex of the second optical surface to the secondary principal plane; SF=distance from the surface of the first optical surface to the front focal point, called the front focal distance; S ...
Vertex distance is the distance between the back surface of a corrective lens, i.e. glasses (spectacles) or contact lenses, and the front of the cornea. Increasing or decreasing the vertex distance changes the optical properties of the system, by moving the focal point forward or backward, effectively changing the power of the lens relative to ...

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 It is approximated by the formula S ( r ) ≈ r 2 2 × R {\displaystyle S(r)\approx {\frac {r^{2}}{2\times R}}} ,
EUGENE, Ore. (AP) — Tre White had 20 points and 11 rebounds as No. 22 Illinois made a resounding statement on the road with a 109-77 blowout of ninth-ranked Oregon on Thursday night.
