zemax can help to design many kinds of optical systems. Here are the basic steps: eSq.GtI

1. make spec for your system 3!]rmZ-W
2. make initial design $!t4r
3. choose glass materials G 3ptx!

4. analysize the abration and image... gcT%c|.
5. modify and optimze them (this is the core of the design). s$j,9uRr

To do these, you need to study basic knowledge of geometric optics.
