The sharp ring stains exhibited by the 6.0 µm FocalCheck™ fluorescent green ring stained/blue 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.
