How much can you focus a standard 5mm LED? (i.e how tight can you get the beam)

If you use the right lens and it is adjustable you CAN focus an led to a nice tight point.

It will not be a laser, but and led just puts our light and light can be focused.

A little distance in front of or behind the focus point and it won't be focused anymore.

There are ways to make the beam almost linear but it still won't be a laser.

So....you can get most of the light into a few strands of fibre optic cable?
