Abstract
A confocal microscope is based on a low mass objective that is driven in one or more axis, with at least one of the axes being driven by a low mass device to provide mechanical scanning of the objective. The scanning mechanism has a low resonance so as to allow the scan length, rate, and range to be easily varied. Control of the objective's position can be either open or closed-loop servoed. The position of the objective can be determined in open-loop systems by calibration, by an internal reference signal coupled with a timing system, or via a means for an absolute or relative determination of the objective's position.
