Practical guide for lens design. Lens design is the technique to find the minimum of a nonlinear equation with tens
to hundreds of variables and tens of restriction conditions. Mathematically, such an
equation does not have an analytical solution, and even a numerical solution can be
extremely hard to find. Before the invention of computers, lens design was a daunting
task and the preserve of a few well-educated and highly experienced experts. It often
took hours of hard work to vary the surface profiles and positions of several lenses in
order to focus one ray to a desired point. The fast computing speed of modern computers
and the development of several commercial lens design software dramatically
simplified the lens design process. Nowadays, even those scientists or engineers who
are not major in optics can try to design some simple lenses.
