D dchurch New Member Nov 5, 2008 #3 Narrow beam IR LED It sounds like you need a LED that has a very narrow beam. I think 10 degrees is about a tight as you will find. Here is a 16 degree that Digi-Key Corporation - USA Home Page has in stock Fairchild Optoelectronics Group part # 1N6264 Digi-Key - 1N6264-ND (Fairchild Optoelectronics Group - 1N6264) I believe a 10 degree LED will focus to about 4 feet in diameter at about 15 feet. If you need a very narrow beam (spot on) look into infraded lasers.
