Hmm. Okay, if that's true, then why would an IR led at roughly identical power as a red or green led give roughly the same brightness? The wii sensor bar uses 850nm and they are very bright, and I've tested with my own Ir LEDs at less than 100mw and they work well.

Why I would need over 100mw of power to get the same dot that a normal laser can give at 5mw? What's so special about IR?

Can you tell me why you would need 100 watt laser to be as bright as a 0.01 watt green laser? The power rating refers to the light OUTPUT power, so that doesn't really make sense to me... I am using an IR-sensitive camera. I'm not trying to magically make IR light visible to the human eye.

Thanks for the replies. The dot is circular focused, and small (maybe 2mm at 6 inches), it comes with a lens that can be rotated so I'm sure of that. At a few inches away, the iPhone camera can see the dot clearly, but it it is small. The center of the dot appears white, so the light's...

I'm trying to find a 980nm laser module with a dot visible to a Wii remote camera at 10-15 feet. The dot only needs to be about the same size and intensity as a normal 5mw red or green laser. I have 4 Aixiz 980nm modules, three at 10mw and one at 35mw. With an iPhone camera (has no IR filter) I...
