I just started an introductory course dealing with geometrical optics for now and maybe some physical optics later (undergraduate level). I've heard that M. Born & E. Wolf's Principles of Optics is a good book. Can you suggest another book? Also, would you suggest the Born/Wolf book for a first approach with optics? I've looked through this forum (Sc. book discussion) and the few threads related to Optics didn't get any answer. I hope to have more luck!
