I am trying to find a really bright infra red led. It needs to be arround the 950nm spectrum so it is invisible to the human eye. I need to provide illumination for a black and white ir sensitive camera. It only needs to illuminate a distance of about 1 metre and powered from a 12v dc source. I can only use 1 led. I have tried a few from Maplins electronics with what i think is the right resistor, but i only get a very dull glow. Nowhere near enough to illuminate anything from 1 metre.
I have tested the camera using the light from a domestic IR remote control which nearly gives enough light.
Can anyone suggest a 3mm or 5mm ir led and the correct resistor ?
the camera specs don`t give me the iR frequency response but it does react to a domestic ir reote control.
