Use caution when experimenting with high power IR LEDs, remember just because you can't see it - doesn't mean that it can't harm your eyes
I want to use these in concert with an IR cam. Some of the smaller leds I've seen don't throw very far and would like the furthest throw possible.
I would imagine that since it's on the low end of the spectrum that it would throw pretty far.
Anyone know that type of info off hand?
Also, any other links out there to IR LEDS?
Thanks

Speaking from experience, it is much more eff and cheaper to use a LOT of 5mm IR LEDs than to purchase some very bright and expensive IR LED
Also, using this method averages out the pattern and gets rid of the die pattern projection problem
Check out OptoDiode, they have some nice parts

It would depend on the CCD chip inside the camera you are using, most are quite sensitive in that area - some even put filters to "tone" down the IR sensitivity on them
Do you have any IR LEDs to "play" with ?

Most B&W CCD cameras (unless they state that they are low-light or IR-illum friendly) DO have a greyish piece of IR-blocking glass or plastic, to keep from getting IR problems in normal useage. Several sites detail what to remove for if you have an old B&W CamCorder, or whatever.

You should be able to go to Radio Shack and purchase the T1-3/4 (5mm) IR LED; if not - I can send you a couple to "play with"

has some interesting info on using camcorders with IR illumination.
