microscope led ring illuminator

Is that a question? or two?

Maybe it's the first line to a poem or song?

Oh, microscope led ring illuminator, microscope led ring illuminator,

How rarely we ruminate your

photons potent upon 'scope stages,

revealing truth to peering sages.

But without you this we know

that truth is lost in dark shadow.

I think he's trying to sell us something. I just can't figure out what it is.
