A calibration device which has at least two targets. Each target has at least one surface exhibiting areas of optical contrast, and each surface has a general plane of orientation. The targets are oriented such that a general plane of orientation of one target is inclined at an angle relative to the general plane of orientation of a surface of the second target which has areas of optical contrast.

Scanning confocal microscope with objective lens position tracking

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.
