What is Microscope

What is MicroscopeStudying and viewing things that range in size through millimeters (1mm ~ 0.04" = 4 hundredths of an inch) to nanometers (1 nm ~ 0.00000004" = 40 billionths of an inch) intrigues everybody and is currently used to every field of technology and science in use today.

Microscopes, devices which magnify, come in an array of forms and use a variety of illumination sources (electrons, light, x-rays, ions and and mechanical probes) and signals to make an image. A microscope could be as simple as a hand held magnifying glass or as complicated as a multi-million dollar research tool.

Making use of these tools, a microscopist explores the relationship of properties and structure of a wide range materials in order to more completely understand the reasons why a particular product behaves the way it does. It is a fascinating discipline which is used to all areas from chemistry and biology to engineering and physics.

Types of Microscopes

The invention of the microscope has brought about excellent inventions that have changed the human race. This product is effective and extremely important in science because it gives opportunity for scientist to study natural components that are not visible to the human eye.

You can find different types of microscopes according to the purpose for which it is intended. Microscopes can be also classified according to their image making physical principles, area of application and versatility. But, microscopes can be comfortable separated into two categories, electron microscope and light microscope. Below is a list of the main types of microscopes.

Light or Compound Microscopes

These types of microscopes are depending on a simple principle of lens and light. A light source illuminates the item while the lens magnifies it so that it may be visible to the human eye for that purpose of studying or evaluating.

Simple Microscope

This is one of the oldest microscopes that utilizes a single lens for magnifying any samples. However, this microscope continues to be regarded as primitive due to its less relevance in serious scientific work. 

Compound Microscopes

This type of microscope works on the identical principle as the simple microscope. However the difference is that it utilizes two various optical parts for the magnifying of objects.

Dissection or Stereo Microscope

This is other member of the optical microscopes that makes use of lens and light. This microscope is various from other types of microscopes because it permits you to view objects in 3D.

Compound Light Microscope

The light microscope (also known as the compound microscope) is referred to as compound because it is made up of two lens systems. One lens system, known as the objective, is positioned close to the specimen and generates an enlarged and resolved picture of the specimen. This image is in turn enlarged by other lens system, known as the ocular or eyepiece, which is positioned close to the eye of the observer. The two lens systems are situated at opposite ends of the body pipe of the microscope.

The objective lens is found at the lower end of the body pipe and usually you can find several objectives, of different magnifying powers, mounted on a revolving nosepiece that permits each objective to be swung into place along the optical axis. 

The magnifying strength of a compound microscope is equivalent to the product of magnifying powers of the objective and the eyepiece. A typical compound microscope can have an eyepiece of 10x magnifying power and objectives of 10x, 45x and 100x magnifying powers. Therefore, the magnifying strength of the whole microscope would vary from 100x to 1000x the size of the actual specimen.
