Caution
The datas entered in the table are saved only if the related "save" button has been activated.
Before saving input datas, all the active cells have to be filled.
R
It is the radius of curvature of a surface. It is either a non null number or "infinite".
n and V
For a refractive surface, the refraction index n is either a number (larger or equal to "1") or a reference of a glass catalog. If the refraction index is a number, the associated constringence is a number strictly larger than "1" or "infinite". If the refraction index n is defined by a catalog reference, its constringence V has to be defined by the same reference. Air and vacuum have a refraction index equal to "1" and a constringence which is "infinite". For a reflecting surface, "mirror" must be entered as the refraction index. In this case, the constringence is the same as that of the previous medium.
d
For the object surface (identified by "obj"), the distance d to the next surface is a number or is "infinite". It is a number for all other surfaces. More details about its sign are provided in the "Coordinate systems and sign conventions" section of the "mandatory parameters" table tutorial.
D
The diameter D of the surface is a positive number. Its value is such that surface boundaries can exist.
V paraxial
If the selected surface type is "thin lens" or "thin lensXY", the V paraxial cell (constringence of the lens) is activated . It can either be a number or a reference of a glass catalog. The medium before and after a thin lens or a thin lensXY is necessary air or vacuum. Therefore, before and after the surface, refraction indexes are equal to "1" and constringences are "infinite".
