who knows how to get those crystals (small ones) for experimenting with wavelengths?
I live in the Netherlands, and I don't know if I can trust the ads on Ebay....
found a IR DL from an old laserprinter, it must be far in the IR, because even with a webcam I can't see the light...
after hooking the receiverdiode up to my scope, the DL seemed to work correctly.
like you test the ir-led of your remotecontrol with a digital camera, webcam or so, you can see the ir-led lighting up.
since the CCD chip ''sees'' more than the human eye.
