The term for these types of microscopes, at least in the industries I've worked in, is an inspection microscope. They're normally lower power than a typical binocular scope like you would see in a biology lab, but work on opaque materials. Inspection scope probably isn't the technical name, but even the vendors have them listed as such. The cheap USB ones work pretty well for home use, just get one that either has a monitor or can hook up to a monitor, the eyepieces tend to suck. For top of the line professional ones, Mantis makes the best ones I've ever used. I think they are in the 2k+USD range though, I definitely don't have one at home.
