Confocal light microscope, artwork. Confocal microscopy uses fluorescent dyes to highlight tissues, cellular structures and proteins in the samples being analysed. A laser beam (blue lines, source at left) is passed through a lens (blue oval) that focuses it on to a beam splitter (grey diagonal line). Some of the laser beams are directed to the sample (bottom right). The fluorescent dyes in the sample are excited by the laser beams and emit fluorescent light. This light passes back through the beam splitter and is collected by a digital camera. Laser beams directed towards the camera are removed by a filter (orange horizontal line).
