Inside the heart of a Light Emanating Diode. Also know as simply an "LED".

The anode plates or "Light Engine" are approximately the width of a human hair.

Different colors make use different Anode Plates shapes.

I've enjoyed some interesting assignments through the years and this is among the most unusual and certainly the most challenging.

White LEDs use a phosphorous coating that obscures the colorful plate inside!

This represents something in the range of 200-1 magnification!
