摘要：
The effect on confocal imaging of spherical aberration caused by a weak refractive-index mismatch is discussed. Aberration balancing that uses a change in the objective's tube length is studied. It is found that the range of depths that can be imaged satisfactorily by a high-numerical-aperture objective with compensation is an order of magnitude greater than that without compensation. The aberration balancing tends to break down for extremely high numerical apertures. (C) 2000 Optical Society of America. OCIS codes: 080.1010, 110.0180, 180.1790, 260.1960, 110.2990.
