Question

One aspect of the history of microscopy can be described as an effort to obtain the highest resolution possible. A major contribution to this effort was the work by Abbe, Rayleigh, et al that demonstrated that an “ultimate” limit to resolution was imposed by the wave nature of light. The earliest microscopes were unable to achieve even this limit. The most advanced light microscopes now resolve considerably below that limit. Describe two different techniques for obtaining this increased resolution.

Explanation / Answer

1) Consider Scanning Electron Microscope Technique where there is a break of electrons reacting with the surface and send signals that gets to give various output signals on the etopography and since there's a possible interaction , it is more precise and even nanostructures can be observed.

2) Trasnsmission Electron Microscope (TEM) is also used with a similar technique where a beam of electrons is passed through a nanofilm to produce an image and with the electron interaction again the material can be studied
