Sophisticated Analytical Instrument Facility

Transmission Electron Microscope
         Instrument Details
Make : PHILIPS
Model : CM200
Specification : Operating voltages : 20-200kv Resolution :2.4 Ao



WORKING PRINCIPLES:

         TEM images are formed using transmitted electrons (instead of the visible light) which can produce magnification details up to 1,000,000x with resolution better than 10 Ao. The images can be resolved over a fluorescent screen or a photographic film. Further more the analysis of the X-ray produced by the interaction between the accelerated electrons with the sample allows detemining the elemental composition of the sample with high spatial resolution.





APPLICATIONS :
           Materials Science/Metallugy
           biological Science
           Nanotechnology
           Ceramics
           Pharmaceuticals
           Semiconductors
