the authors develop the wide range scanning tunneling microscope (stm) to measure surface topography of a diamond turned gold mirror on a gold coated float polished glass surface. three dimensional positioning of the stm device is achieved by monolithic high precision wide range translation mechanisms called multi-compound parallel springs. one of the strong points of this device is that capability of this specially fabricated x-y stage is to measure over a sample area of 70 mu m*70 mu m and is easily cut from a monolith. each diamond tip trace on the turned surface using a high precision air bearing lathe changes noticeably. this fact shows that we still have to improve not only such manufacturing conditions as tool radius, and the roughness of tool tips but also the surface finish machine environments especially vibrations
