The sharp ring stains exhibited by the 6.0 μm FocalCheck™ fluorescent dark-red ring stained/green throughout microspheres produce a striking visual representation of instrument misalignment or other aberrations making them ideal as reference standards for confocal laser-scanning microscopy. Correct image registration is indicated when the ring image and disk image of the combination beads are perfectly coincident in all dimensions.
