range of 123 μm in a commercial confocal microscope at 0.5-0.64 NA. The MEMS mirror is
much faster than lens or stage translation allowing synchronization to xy scanning for agile
control over the 3D shape of the surface that is scanned. We describe a novel, low-actuator-
count MEMS mirror designed specifically for focus control in scanning laser microscopes
and present images taken with the mirror deployed on an Olympus Fluoview FV300.
