Hi Rory,
have you considered a regular (non-resonant) galvo for the stripe removal?


It should still be fast enough to do more than several round-trips during a
10 ms exposure, so it should be quite effective in stripe removal even
without fancy synchronization between the galvo and the camera (depending on
the mirror size and the deflection angle you need in your setup...).

Best, zdenek

Hi Confocalists,

We’re trying to circumvent the annoyance of resonant mirrors screaming at 8
kHz. I was wondering whether anyone has a recommendation for constructing
soundproof containment?

Generally were using inexpensive resonant mirrors from EOPC: http://www.
eopc.com/sc30.html

Also, does anyone know whether the more costly resonant scanners used for
confocal/multi-photon laser scanning microscopies are any better in this
regard? Were not hugely concerned with other attributes (simply for light
sheet microscopy stripe suppression) just the piercing noise.

Many thanks in advance!

Rory
