Impressive images. I just wonder how such a worn stylus would look like in the traditional USB microscopes used. I have no such worn stylus to view, and even old stylii does not show signs of such wear.ray_parkhurst wrote:In the "Microscope?" thread (viewtopic.php?f=19&t=92795 I posted some images of stylus tips showing the contact points and shapes as viewed directly down at the stylus tip, with lighting at the correct angles and placements to show contact shape and any wear patterns. Rather than hijacking that thread further, I figured I'd start my own. You can view my early attempts on JICO N97LTDE and Shure N92LT styli, with explanation of the photo technique, over on the Microscope? thread.
First stylus I will show here is a well-worn Shure M99E. This stylus is so worn that the tip now rides all the way to the bottom of the groove! The fairly polished elliptical flats on this stylus were transparent enough that the surfaces did not image well, and this confused the stacking program in those areas. But the wear pattern is unmistakable, and that's the interesting part of this image:

Old one, but how worn? - that is the question.
