Design software for these sorts of optics usually costs several thousand dollars and requires a pretty high degree of optics knowledge to operate competently. Look for books on illumination optics, like this one, for instance:

Look into software packages like Optistudio, FRED, or TracePro, and prepare yourself for the long journey ahead.
