The difference is that the optics curriculum goes into more depth regarding the applications of optics, for example a class on aberrations. The optics curriculum is more of a specific treatment of the physics of light, instead of a general undergraduate physics curriculum. Additionally, the optics classes are an introduction to geometrical optics, physical optics, computational methods, quantum theory of optics, aberrations and interferometry, EM theory, an advanced mathematics class, and an optoelectronics class, as well as various laboratory classes. From the BA, I will have also taken thermodynamics/statistical mechanics, classical mechanics, gravitation and general relativity, and a general quantum class, instead of the quantum theory of optics. I guess the real question comes down to this: does your degree specifically matter, versus the classes you take. But I think that might have been answered in a different post.
