I have tried all kinds of things to get sidelight imagery. Some tricks seem to work for me.

Using sidelight does pick up details otherwise missed.

Looks good Don. What? No mirrors_ 😃
I wonder. What happens if, when you are using the flashlight for top lighting, you put a mirror on the stage under the slide?

Just one more question....
Would you achieve low grade fluorescence using a uv flashlight or if sanitizer?

yeah maybe uh just be careful you dont use a bunch of precision lenses to focus concentrated UV radiation directly into your eyeballs
