The optical imaging technique of Laser Confocal Scanning Microscopy (LCSM) is used to increase the optical resolution and contrast of an image. Although laser scanning is most commonly used, the scanning process is relatively slow and requires high light levels that may produce photo-damage, particularly in living specimens. Spinning disk confocal microscopy uses a wide illumination field that is projected through microscopic apertures in a rotating disk to generate a scan pattern. This parallelizes the scanning process, making it faster. Confocal imaging is compatible with many spectral applications including multi-fluorescence imaging, time-lapse imaging, FLIM, FRAP, and FCS measurements.
