collimator for maglite?

Does anyone know where I can buy a 2" collimator lens for a maglite (I guess that's what you call them collimators? It was flat on bottom rounded on top.)

My buddy found a busted telescope and took all the lenses out of it. He gave me one that was 2" wide and it fit perfectly into my maglite. It did some really wild things to the beam.

I was wanting to buy a collimator to get a beam from my maglite something like the Aurora 1.5 Watt, no spill, no spot, just a very distinct circle of light.

Thanks
