Iowa State University recently acquired a Laser Scanning Confocal Microscope. The microscope is located at 1082 Veterinary Medicine in the Image Analysis facility. Confocal microscopy is an improvement over conventional light and fluorescence microscopy in that a finely focused laser beam that rapidly scans the specimen at a single depth illuminates the specimen. Only a thin plane is illuminated within the object, and objects outside of the plane have little effect on the quality of the image. The result is a crisp, blur-free image. Images from optical sections taken at different depths can be stored in a computer and used to reconstruct a three-dimensional image of the entire object.
