paraxial conjugation


conjugation for a given object and a thick lens


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.
e is positive.
Raddii and x 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.

conjugation for a given object and a thick lens
n : refraction index R1 : radius of curvature of the first surface R2 : radius of curvature of the second surface e : center thickness x : distance from the first surface vertex to the object point l : distance from the first surface vertex to the primary principal plane li : distance from the second surface vertex to the secondary principal plane s : distance from the primary principal plane to the object point si : distance from the secondary principal plane to the image point xi : distance from the second surface vertex to the image point m : magnification
