Using dictionary definitions is inappropriate in this context. For
example, my American Heritage says "Refracting light without spectral color
separation" for "achromatic"; if you take that at face value it is better
than apochromatic! Fortunately, there are careful, technical definitions
of these terms. They are the ONLY ones that are meaningful in this
context.
