ABSTRACT:
Provided is a stage on which to place a sample, which is capable of performing a high-precision positioning at a short time, and which prevents an image drift of a measuring object. The stage includes: a base having a guiding unit; a table which moves in a movement direction along the guiding unit; a motion unit which provides motion in the movement direction in order to cause the table to move; and a transmission unit for transmitting the motion to the table. In the stage, the transmission unit includes a table block fixed to the table, and a motion block fixed to the motion unit; and the table block and the motion block contact each other at two points forward and backward in the movement direction while in motion, and are separated away from each other while not in motion.
