The Model T200 Scanning Microscope has been developed under the design philosophy of combining simple Operation, simple maintenance, and high performance. Accordingly, quality micrographs comparable to those obtainable by a large instrument can be readily obtained without any special skill.
These features together with the various advantages peculiar to the scanning microscope, such as very large depth of focus, wide magnification range, and minimal specimen preparation, make the T200 a most effective instrument for research work, quality control, and as a visual education aid.
GENERAL
The scanning electron microscope is a comparatively recent addition to the microscope family and is proving to be very popular along with the long established light and transmission type electron microscopes.
In spite of their merits and demerits, each type of microscope has its role to play depending on the field of application. For example, if a high resolving power and large depth of focus is not called for, a light microscope would be ideal. Where a very high resolving power is required, a transmission electron microscope would be necessary. However, when using a transmission electron microscope, the specimen must be very thin (less than 1 um (10,000 Ä) in thickness), a factor which requires a great deal of skill on the part of the user in order to prepare such specimens.
The scanning electron microscope, on the other hand, offers a fairly high resolution and moreover, since it is possible to use bulk specimens (specimen thickness being of no consequence), specimen preparation is easy. In addition to which, the depth of focus is large, thereby enabling 3-D observation.
The operational principle of the scanning electron microscope is illustrated in Fig. 1.1. A finely focused electron probe is made to scan the specimen, resultant upon which, secondary and backscattered electrons, etc. (Fig. 1.2) are emitted from the surface of the specimen. These signals are then detected by a detector and outputted via an amplifier to a synchronously scanned CRT as an intensity variation signal. The CRT raster width divided by the electron probe scanning width gives the Image magnification.
By adding an appropriate detector (optional) to the Standard T200, transmitted electron images, cathodoluminescence images, etc. can be observed in addition to secondary and backscattered electron images. Further, by incorporating an X-ray detector, X-ray analysis becomes possible.
