Types of Microscopes
Microscope is one important tool that is functional to see objects or organisms that are so small
. Along with the progress of science and technology, types of microscopes and zoom capabilities experience the advance.
There are two types of microscopes; light microscope and electron microscope. Light microscope include bright field microscope, dark field one, phase contrast one and florescent one. Microscope that is often used in secondary schools for the practicum is bright field microscope.
Bright field microscope is a microscope with a field (field of view) that surrounds the specimen appears bright, while the specimen looks darker. This is because light from the source (mirror or lamp) passes through a lens system to the top without experiencing a change, thus it forms the bright field.
Microscopes in common use today use two or more lenses (lens system) such as ocular and objective lenses to enlarge the object. The types of this computer range widely, from a simple one for the purposes of secondary school up to a fairly sophisticated one for research purposes.
The main characteristic of the microscope today among others is monocular with the upright and tilted tube, binocular, trinocular, the power of the lens that is used, the light source (using a lamp that is attached), and even the camera that can be mounted (video camera) on trinocular microscope and can be connected to your TV.
Meanwhile, electron microscope has the highest magnification. It can amplify a tiny thing up to 500.000 times. It uses electron in the place of light in light microscope.
