Superachromat is the term you're looking for in terms of lenses corrected throughout IR to UV. They're not actually that expensive if you know where to look, I got my Zeiss 250mm supeachromat for about $500 from a Japanese seller. Works a treat for full spectrum film work especially on a system that lets you swap between film backs, if not for the woeful cost of film these days.
