400 micron fiber sucks. Take it from some one who has been there, got the Tee shirt, done that, and ignore this. Not with a nice Dilas, but one of their inferior competitors. 25mm mirrors barely work as the X mirror. In fact you will have vignetting (clipping) as the mirror moves. The Y mirror has to be even bigger. 400u is a flashlight. You have to mask off over 40% of the beam diameter to fit the low divergence portion on the mirror.
That laser cluster is for video projectors...
Show producers demand fast scanning these days. Useful fat beams are provided by cheaper MSR series lamp sources.
200u is a bear and is marginally useful at best for beam shows. Even then you still end up masking about 30% power to make it useful.
