Did you know that Silicon is transparent to IR at wavelengths above ~1100nm? Here I have 5 IR LEDs beneath and above a silicon die. First you’re seeing the visible light which I then turn off so you can see the IR shining through with a camera that has no IR filter.

Anyone else blast lasers into silicon when they're mad?
