. Amicrotome (from the Greekmikros, meaning "small", andtemnein, meaning "to cut") is a tool used tocut extremely thin slices of material, known as sections. Important in science, microtomes are used inmicroscopy, allowing for thepreparation of samples for observation under transmittedlight orelectron radiation. Microtomes use steel, glass, or diamond blades depending upon the specimen being sliced and the desired thickness of the sections being cut. Steel blades are used to prepare sections of animal or plant tissues forlight microscopyhistology. Glass knives are used to slice sections for light microscopy and to slice very thin sections forelectron microscopy. Industrial grade diamond knives are used to slice hard materials such as bone, teeth and plant matter for both light microscopy and for electron microscopy. Gem qualitydiamond knives are used for slicing thin sections forelectron microscopy. Microtomy is a method for the preparation of thin sections for materials such as bones, minerals and teeth, and an alternative toelectropolishing andion milling. Microtome sections can be made thin enough to section a human hair across its breadth, with section thickness between 50 nm and 100 µm......
