Lagrangian,
Thanks again for the informative post! I’m certainly no expert in microscopy either but I’ve read a few things here and there that agree with what you’ve said, especially about the limits of what can be achieved with optical scopes. I think you can see features below .2um but they are fuzzy at best, you just get the hint of them and I’m sure you’re right that you can’t state measurements in that range with confidence. For my purposes, I’m pretty content with this level for now as it at least helps me visualize more clearly what’s going on with some of the finer grits. It’s also helpful for analyzing different techniques like edge-leading vs edge-trailing. Once of these days, I’ll have to scheme regular access to and SEM 🙂
