Laser microtome
The laser microtome is an instrument used for non-contact sectioning of biological tissues or materials. In contrast to mechanically working microtomes, the laser microtome does not require sample preparation techniques such as freezing, dehydration or embedding

Advantages and disadvantages
A disadvantage encountered with the SBEM method is that the thickness of the slice which can be removed with the ultra-microtome Because cutting by the ultra-microtome is extremely fast (comparing to the milling process in FIB-SEM), it can expose a wide area of the material (x and

Imaging
The sample may be cut into thin slices with a microtome, then imaged using transmission electron microscopy. Alternatively, the sample may be imaged with a scanning electron microscope, then the surface abraded using a focused ion beam, or trimmed using an in-microscope microtome
