What about needing to evenly diffuse IR?

I need to have an omnidirectional source relative to a plane using a
single LED.  You know those flashlights the ground crew uses to
direct an airliner into the gate?  How they have a sort of tube or
cone clipped on to make a nice torch effect?  I've wondered if I
could insert the LED into a small solid tube of styrofoam or some
such to spread the IR out evenly in all directions...or at least all
directions on a plane.

What material would efficiently diffuse the IR this way?  Or is there
a better way (other than using  multiple LEDs)?

Phil
