1. make sure you have some broadband IR goggles.
2. Use your camera. If it doesn't have an IR filter, it will work. If it does, use your cell phone camera. If you don't use a webcam.

Nice find, But it has to be invisible so past 800nm's, or i guess if it looked like a 1mw red then it would be fine. i could say see the weak dot ? and then i put a match and it lights in 1 second !!
