Micrographs need scale bars or horizontal field width (HFW) labeled, period.
Fortunately, in this place at least, it's not going to be used for scientific or engineering purposes.
I'll have a look at the source, though, & see whether I can't find something.

You aren't going to approve of this atall-atall : there's nothing in the treatise it's from as to those kinds of thing! ... neither as annotation, nor in the body of the text. It does however say "taken using a JEOL 5900 SEM in backscatter mode".
I've cited & linkt-to the source, now ... which I ought to've done in the firstplace.
I have done too much SEM to be impressed. Just makes me feel numb and tired.

The previous commentor says this also.
