Please have a look at the spacing of these equations
- $[]_{\langle n\times m\rangle}$ (the brackets touch)
- $Z_{F1}$ (F and 1 spacing)
- $\frac{L_L}{L_R}$ (the subscript L too close to the fraction rule)

The $\frac{L_L}{L_R}$ is not a font issue. Things are just as bad for
Computer Modern (actually, slightly worse for Computer Modern); it's a matter of how TeX sets fractions in this (somewhat strange) situation.
Notice that for a displayed equation $$\frac{L_L}{L_R}$$ there is no
problem at all. If you really want $frac{L_L}{L_R}$ rather than
$L_L/L_R$, then you would have to adjust spacing yourself (for example, by replacing the _L with something like _{\astrut L} where \astrut was
some strut that had some extra depth to move things up).
I guess I could go and add kerns for upper-case letters and the numeral 1 (which has more space on each side than the other numerals). I'm interested to know how this expression arises. It's uncommon to have a character {\it followed\/} by the factor 1. [Also note that, if you know a bit you can always go in and change any kerning that you would like to adjust to your own specifications: use tftopl to go from mt2mi*.tfm to
mt2mi*.pl, go into mt2mi*.pl with any reasonable text editor to change, or add, a kern, and then use pltotf to go back to the mt2mi*.tfm.
As for $[]$, yes the brackets [almost] touch, but even the brackets in
Computer Modern almost touch. Are you sure this is what you really want, and not something like $[\ ]$ or $[\,]$, etc?
