I am modeling a laser pointer in Blender, but I am not sure how to make the laser's light beam.
The Spot light comes the closest to what I am looking for, but its starting diameter is 0, and you cannot set the spread amount to less than 1 degree. I would like to be able to do this in the Cycles rendering engine if possible.
Edit: I am not trying to see the actual beam of light, like when you shine a laser beam through fog. Rather, I simply want to have the light beam go straight from the laser. So that if you were to shine it at an object up close, the dot would be the same size as if you were to shine it at a object farther away.
Not this: But this:
