Any use for a beautiful TEM00 spot?

Beyond admiration of the spot shape. I know I may need or want TEM00 later on. Just don't know if I can justify the cost building myself a rudimentary spatial filtering setup in a project enclosure lol.

That really depends on the application..

TEM00 is necessary for certain scientific, holographic, and industrial uses, but for most entertainment uses it is not worth the effort and losses presented by the process of obtaining TEM00 output.
