Fluorescent 190 nanometer diameter polystyrene spheres imaged through laser scanning confocal microscopy ( animated version). The image illustrates the distortion of axial (z-plane) resolution due to spherical aberration arising from an index mis-match of the mounting media. The spheres were imaged through 20 microns of glycerol-gelatin using a 63x 1.32NA oil immersion objective and 543 nanometer wavelength light. The field of view (each frame) is 740 nanometers.
