Caution

Fill in all input cells.

Choose all parameters unit.

n0, n1 and n2 can be either values or references of glasses from the catalog.
If values only are 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.

n0 : refraction index of the first medium
n2 : refraction index of the second medium
n1 : refraction index of the lens
R1 : radius of curvature of the first surface
R2 : radius of curvature of the second surface
e : center thickness
x : distance from the vertex of the first surface
to the object
l : distance from the vertex of the first surface
to the primary principal plane
li : distance from the vertex of the second surface
to the secondary principal plane
s : distance from the primary principal plane
to the object
si : distance from the secondary principal plane
to the image
xi : distance from the vertex of the second surface
to the image
m : magnification

Note

This calculation page can not detect all unrealistic inputs.
