Any IR LED between 850 and 950 nm will be fine. Other factors to take into account include intensity (how bright/powerful the emitter is) and the Angle of half intensity (how narrow the IR beam is). These specs will be included on the emitters datasheet. In general get as strong as you can with as narrow a beam as you can. Cheers KG |
