This approximation is correct, accurate, and valid. It works perfectly, except that it is only correct, accurate, and valid when the collimnated light enters the lens at a zero angle.

A fourth iteration would be simple, in theory. The light would have to enter the lens assembly at some angle <math>\theta</math> which could be input by the user. Since

The fourth iteration is elementary. The light is now allowed to enter the lens assembly at a selected angle <math>\theta</math> which is input by the user. Since
<math> \tan{\theta} = \frac{c}{f _2}</math>
<math> \tan{\theta} = \frac{c}{f _2}</math>
