chromatism


axial chromatism by a spherical refracting surface


Caution
Fill in all input cells.
Choose all parameters unit.
Refraction indexes can be either values or the reference of a glass from the catalog.
If values only are entered, the wavelengths will not be considered.
Object position and radius are algebric or infinite. Enter "infinite" for a plane surface or an object at infinity.
Positive direction is according the horizontal arrow in the bottom right of the scheme.

axial chromatism by a spherical refracting surface
ns0 : refraction index of the first medium corresponding to the smallest wavelength nl0 : refraction index of the first medium corresponding to the largest wavelength R : radius of curvature of the surface ns1 : refraction index of the second medium corresponding to the smallest wavelength nl1 : refraction index of the second medium corresponding to the largest wavelength x : distance from the vertex of the first surface to the object point dxi : axial chromatism of the combination
