1.1 Overview
The TM3000 is a tabletop microscope operating under the principle of low-vacuum
observation, wherein a narrowly focused electron beam is directed onto the specimen, the
resulting backscattered electrons are detected, and minute parts of the specimen are
enlarged for observation. The main features of the system are the capacity to permit
specimen observations in high-magnification regions beyond the reach of an optical
microscope and the ability to produce three-dimensional like images emerging from a great
focal depth. By downsizing a conventional electron microscope and simplifying the
operations, the Tabletop Microscope invites users who have never touched an electron
microscope before to use it as a handy tool. The TM3000 represents considerable
improvements in performance and functionality over the previous Model TM-1000 Tabletop
Microscope, offering a truly easy to use high-performance system.
