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>

the equation would be very simple to appropriately modify to take this into account.

This step is currently under construction and is nearing completion. This page will be updated to reflect this within the next few weeks.

This equation forms the basis of the fifth iteration.
