Optical microscopes use graphic light and a system of lenses to magnify small samples that are usually un-seen to the bare eye. The optic microscope is the first, oldest and simples type of microscope (as opposed to the much more industrialized electronic microscope). The first optic microscopes were created in the 18th century. Due to it's contract sizes, simplicity and relatively low price, the optic microscope is very popular, and can be found in use in many areas of biology. optic microscopes mostly magnify objects for up to 1500 times.
The first optic microscopes were structured in a way that is called "the straightforward microscope". This structure utilizes only one pair of lenses to originate a magnified image of the sample. Today, the straightforward structure is in use only in the magnifying glass, hand lens and the loupe.

The more advances optic microscopes, and the ones that are beloved today, are what's called "compound optic microscopes". These microscopes use a system of many lenses, in order to "compound" and multiply the magnification, and therefore maximize it. The two main lens systems in an optic microscope are the objective lens (near the examined object), and the eyepiece lens (up near the eye of the scientist). Contemporary optic microscopes use multiple lenses both in the objective part as well as the eyepiece part.
The old optic microscopes also used a mirror to provide illumination below the object. The Contemporary optic microscopes use a strong lamp to provide constant and strong illumination.
So what are optic microscopes used for now a days?
The main uses of aggregate optic microscopes include:
The examining small pieces of material, or even a smear or a squash preparation. This is due to the fact that the optic microscope uses light to pass beneath the object and enter the lenses. That's why the item is good be half-transparent. In other uses the optic microscope may be used to peruse metal samples, in order to study the metal's structure.
At low power, microscopes can be used to peruse small living animals and plants. At high power, they can be used to peruse bacteria.
It is leading to note that the vast advancement in healthful fields and biology in general, is owed to a large extent, to the invention of the optic microscopes. For example, the way the blood flows in our body was not fully understood until the microscope made in inherent to peruse small blood vessels behavior.
