Please be careful around invisible lights sources in general, and lasers in particular. In order to see near IR radiation, you'll probably have a LOT of it entering your eye, and if the source is collimated it will come to a focus at the back of your retina. This can cause damage at VERY LOW power levels. I haven't played with laser diodes but I do work with gas lasers, and have heard enough horror stories. Please read up on the safety considerations for IR lasers and buy the proper eauipment. I believe you can purchase a material which converts the IR into visible light, and presumably diffuses it too. I think it's relatively inexpensive. joel
