I think Vishay makes some very nice, high power IR LEDs. One series peaks at about 880 nanometers wavelength (good camera sensitivity) and one series peaks at about 940 nanometers (completely invisible ot the human eye and a bit stranger images like some clothing looks somewhat transparent).
There are loads of infrared webcams being sold on ebay (from hong kong mind you) but any standard webcam can pick up an image from within the infrared spectrum...
Anyone experimented with making their own infrared camera?
What light sources did you use and were they strong enough to capture an image between 3 and 20 feet away (1 to 7 metres)?
I was thinking about infrared LEDs.... Anyone know a UK (or EU) source for strong IR LEDs?
Be an interesting project if it works given the infrared webcams on ebay are around £30 on average (£50 in the shops..)
Regards
Pete
