Balancing Scanner Mirrors (what's this brown stuff on the mirror?)

This video discusses and demonstrates our mirror balancing technique, and illustrates what can happen if the mirrors are not balanced. At ScannerMAX, we balance most mirrors that ship. The only time we don't is if the application involves waveforms that can't possibly excite cross-axis bending modes of the rotor/mirror combination.
In person, when viewing by eye, the difference is much more dramatic than it's showing up in this video. If you look closely, even toward the end of the video the R shows some distortion. Once the tape has been removed, you can actually hear the difference too. If you listen carefully, the scanning is noticeably louder once the tape has been removed.
(By the way, there was a heavy thunderstorm in the background, and that's the crashing sound you were hearing...)
Here's the "demo-effect" I was talking about. Good thing that didn't happen in my video!
