A micrometer, also called a micron (µ) is equal to 10-6 m, i.e., 1/1000th mm. Q.2. What is a Nanometer (nm)? Ans. It was formerly called millimicron (mµ) and is equal to 10-9 m or [...]
In this article we will discuss about the design of atomic force microscope, explained with the help of a diagram. An atomic force microscope instead of using a lens is provided with a probe to examine the surface of a specimen with a sharp tip which may be several micrometers in and less than 10 nm in diameter at the [...]
In this article we will discuss about the design of transmission electron microscope, explained with the help of a diagram. In TEM a finely focused beam of electrons from an electron gun is passed through a specially prepared ultra thin section of the specimen. The beam is focused on a small area of the specimen by an electromagnetic condenser lens. [...]
