The confocal laser-scanning microscope (CLSM) has enormous potential in many biological fields. When tests are made to evaluate the performance of a CLSM, the usual subjective assessment is accomplished by using a histological test slide to create a “pretty picture.” Without the use of functional tests many of the machines may be working at sub-optimal performance levels, delivering sub optimum performance, and possibly misleading data. In order to replace the subjectivity in evaluating a confocal microscope, tests were derived or perfected that measure field illumination, lens clarity, laser power, laser stability, dkhroic functionality, spectral registration, axial resolution, scanning stability, PMT quality, overall machine stability, and system noise (1-3). It is anticipated by using this type of test data, performance standards for confocal microscopes will be obtained and the current subjectivity in evaluating CLSM performance will be eliminated.
