Are there any specific infrared LED's that have a narrow "beam width" when emitting? If not, does anyone know of a way to constrain it? A lens perhaps?
I would like to control the beam width over a distance of about 2 ft. I might need to go with a laser emitter....
Any suggestions would help.
Thanks,
