Microscope Parts and Functions, Types, Parts

Microscope an instrument which is used to see very small things that cannot be seen with the naked eye. When we look at something through a microscope, it appears larger. Using it, we can view an object up to 1500 times bigger than its original size.

Structure of a Microscope

A light microscope has a base an arm, a tube, a stage and two adjustment screws two lenses are fitted on the two ends of the tube.



The end of the tube through which we observe an object is called an eyepiece.

Objective Lens:

The lens near the object to be seen is called an objective lens. Light is passed through the object from below using a mirror.

Glass Slide:

The slide is a rectangular piece of glass. The object is placed on it to observe under the microscope.

Electron Microscopy

Max and practical Ernst Ruska built the first electron microscope in 1931. Transmission electron microscopes facilitate Morphological information at the scale of an atomic diameter. And also facilitates the observation of crystallographic and other Biochemical details within a few Square Nanometer areas

In which, the specimen must be prepared in skinny Section because a beam of the electron is transmitted through the sample to produce images on a phosphor screen.

In the present thicker area of the specimen Where fewer electron avers transmitted and conversely, light regions of the image represent thin areas on the sample.
