Confocal Microscopy

Confocal Laser Scanning Microscopy (CLSM) is one of a series of methods to generate slices from microscopic samples by means of optics. The sample stays intact, and the slicing may be repeated many times. True Confocal Scanning (TCS) is a technique, where only a single, diffraction limited spot is illuminated and observed at a time. The benefit of confocal imaging is a dramatically increased contrast by removal of out-of-focus haze. Z-sequences of optical slices (3D image stacks) are sources for subsequent rendering as anaglyphes, depth-coded maps or 3D movies. TCS is also very well compatible with multi-fluorescence imaging, time-lapse imaging, FLIM, FRAP and FCS measurements – plus a whole world of spectral applications.
