Compound microscope was made by John Cuff in 1750. It is known that nowadays, there are some microscopes available in the world. They are simple microscope, light microscope, electron microscope, and camera microscope.
Light microscope uses three types of lenses. They are the objective lens, ocular lens, and condenser. Objective and ocular lenses are placed on the ends of the microscope tube. The lens of microscope could be a singular lens (monocular) or double lenses (binocular).

At the end of microscope, there is a place that holds the objective lens that can be fitted with three lenses or more. And, there is an object table under the microscope tube.
The function of objective lens is linked to the formation of the first image. This lens also determines the buildings and the trace that will be seen at the final shadow. It is also able to expand the image of the objects, so it can view the trace that is placed closely as two isolate objects.
Meanwhile, ocular lens is a microscope lens that is placed at the tip of the tube, close to the eyes of observers. This lens functions to expand the image produced by objective lenses.
The third lens system is a condenser lens. Condenser role is to illuminate the object and other microscope lenses. This lens also supports the creation of lighting on an object that will be seen, so you can get the maximum divorce power with the allowable settings. If the divorce power is less maximum, two objects will appear to be one and the magnification will be less optimal.
From a variety of microscopes, electron microscope has the top magnification. It can expand objects up to 500.000 times. Distinct from the light microscope, this microscope uses electrons instead of light.
Meanwhile, camera microscope is a new innovation of object observation. This system allows the ease and convenience of microscope data observation, especially for observation that involves many observers at the same time. The new innovation in this system includes the innovation in terms of appearance and data warehouse in the form of electronic data. Using this microscope, the visualization of minute observation can be displayed straight through the television screen, Lcd/ Dlp projectors, or computers. Its visualization can also be saved as a photo or movie.
