A Microscope is an instrument used to see objects that are too small to be seen by the naked eye.

Microscopy is the science of investigating small objects and structures using a microscope.

Microscopic means invisible to the eye unless aided by a microscope.

There two kinds of microscopes that you can identify in any
laboratory. They are the simple and compound microscopes
magnify an object directly, and on the other hand, compound
microscopes magnify an object, and show the objects in their
reverse position. You can observe that what is left in the image is
right in the object when moving the slide in a certain direction.

There are many types of microscopes that you can find in the
market today. All you need to do is to determine what it is used for.
The different types of microscopes and their basic functions are as
listed below.
• Complex Compound Microscope: Light or optical types of complex compound microscopes combines objective, eyepiece lenses, and light condemner lens and magnify the image of
small objects.

Simple Compound Microscope. A simple compound microscope is similar to complex compound microscope in function. However, the difference is that a simple compound microscope, is most used to magnifying objects generally. It has no light condenser attached beneath the stage as compared to complex compound microscope.

Stereo / Dissecting Microscope: A stereo or dissecting microscope, combines two objectives lenses, and two eyepieces to view an object. When you use this microscope, you will see
three-dimensional images of the object on the stage.

Fluorescence Microscopes: Fluorescence microscope is a special
microscope that uses fluorescence and phosphorescence lights to view samples and determine their properties.

• Electron Microscope: An electron microscope is one of the most sophisticated types of microscopes with highest magnification (10,000X – 2,000,000X). Electrons used to illuminate the smallest particles, which passed through magnetic field onto a photographic film. When the film is developed magnified
images of the particles appears. We have two types, the Transmission Electron Microscope (TEM), and Scanning Electron Microscope (SEM). They are useful for bacteria and studies on Viruses etc.

Digital Microscope: A digital microscope you will see has a digital cameral attached to it and connected to a computer screen to view the object directly. It has the advantages of taking the picture of the object as well.

Digital Imager Microscope: This imager microscope (Fig 1.7) is a type of digital video capturing microscope you mount on compound microscope, and connect with USB or AV cable to record the activities of mobile specimens.
