spherical aberration


schmidt plate correcting the spherical aberration of a spherical mirror for an object at infinity


Caution
Fill in all input cells.
Choose all parameters unit.
n can be either a value or the reference of a glass from the catalog. If a value is entered, the wavelength will not be considered.
The aperture stop and the Schmidt plate are located at the mirrors center.
All parameters are positive except de which is algebric.
Positive direction is according the horizontal arrow in the bottom right of the scheme.

schmidt plate correcting the spherical aberration of a spherical mirror for an object at infinity
R : radius of curvature of the mirror n : refraction index of the Schmidt plate D : clear aperture h : height de : difference between the Schmidt plate thickness at height h and its thickness on the optical axis
