Leica SP8 UV/Visible Laser Confocal Microscope

Confocal microscopy permits one to optically section a fluorescent sample (such as a cell that has been stained with contrasting fluorescent dyes) with superior resolution by using a pinhole to reject light that originates outside of the chosen area. By collecting a series of such images through the depth of a sample, the user may assemble a highly accurate three-dimensional reconstruction of the entire sample.
