I have a sheet of metal that had grooves cut by laser in it; I need to analyze the depth of the grooves, and for that I think I will need to obtain a thin section slice of the metal and then put the sample under a microscope.
A microscope is not a problem to get, I have access to several. But my biggest issue here is how to obtain the section slice. Has anyone had experience doing something like that? I know that a microtome is used for obtaining very thin slices of biological samples, but not metals, I think. How do I slice the metal? Or is there perhaps a better, easier method of measuring the grooves' depth?
