What devices have you found useful when inspecting your stylii for cleanliness?

Please do not describe how you clean your stylii once you have discovered they are dirty.  Make that another topic!

I am interested in what you have found useful during your inspection.  My Audio Technica microline stylus is so small I can hardly see it at the best of times.  To make things worse for me, I need reading glasses and my current tone arm is a fixed head-shell design so I cannot easily get a good viewing angle - the arm does not tilt much!  Also the background, mainly a black mat, does not offer a good contrast.

Suggestions please ....
