Sorry it took so long, but here they are: scale bars. To accomplish this, I took pictures of 50, 125 and 250 micron wire from California Fine Wire at 4x, 10x, 20x, 40x, 60x, and 100x magnification. The wire has a thin coating of polyimide insulation (~3-5 microns thick) that can be seen in the higher resolution 50 micron wire images. These images were taken on the same scope, with the same camera and objectives, as all of the previous IC Friday images, so the image dimensions are exactly the same for each magnification. I didn’t bother with 60x and 100x for 125 and 250 microns since their diameter was larger than the field of view.
