ABSTRACT:
A microtome particularly suitable for sectioning specimen to be observed on a transmission type electron microscope. Mounted on top of and located to one side of a machine base (2) are an X-Y axis stage and a tilting stage (4) which in turn supports thereon a cutter holder block (5) with a cutting knife (6). Located to the other side of the machine base (2) is a micro-feed mechanism (7) which supports thereon a specimen holder support arm (12) with specimen (14) and a Z-axis stage (11). The micro-feed mechanism (7) has first and second linear motor stages (8) and (9) to be displaced inversely in intersecting directions crossed each other with a predetermined intersection angle (28) across Y-axis. As the first and second linear motor stages (8) and (9) are displaced at the intersection angle (20) with each other, the specimen (14) is displaced over a small distance of nanometrically fine level in the direction of X-axis, thereby permitting to produce an ultra-thin specimen piece.
