The space disappears if you remove the ColorFunction gradient from the plot parameters.  Also, if you change \[Mu] to a standard character like m, the formatting looks perfectly acceptable.  To be honest, I don't really understand the reason for the [#] & following the ColorData tag, but the gradient doesn't seem to work properly without it.  Is my syntax correct?

I got it to render ok (V7.0.1 on OS X 10.5.7) by adding an invisible
space:

(\[Mu]\[VeryThinSpace]m)

...but I'm not sure why the problem you've reported occured.

ColorFunction -> "VisibleSpectrum" is all you need.
