History And Uses Of optic Microscopes

Optical microscopes use descriptive light and a theory of lenses to magnify small samples that are regularly un-seen to the bare eye. The optic microscope is the first, oldest and simples type of microscope (as opposed to the much more advanced electronic microscope). The first optic microscopes were created in the 18th century. Due to it's ageement 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 buildings utilizes only one pair of lenses to generate a magnified image of the sample. Today, the straightforward buildings is in use only in the magnifying glass, hand lens and the loupe.

Microscope

The more advances optic microscopes, and the ones that are favorite today, are what's called "compound optic microscopes". These microscopes use a theory 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). Modern optic microscopes use manifold lenses both in the objective part as well as the eyepiece part.
The old optic microscopes also used a mirror to supply illumination below the object. The Modern optic microscopes use a strong lamp to supply constant and strong illumination.

So what are optic microscopes used for now a days?
The main uses of composition 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 better be half-transparent. In other uses the optic microscope may be used to witness metal samples, in order to study the metal's structure.
At low power, microscopes can be used to witness small living animals and plants. At high power, they can be used to witness bacteria.

It is prominent to note that the vast advancement in corrective 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 possible to witness small blood vessels behavior.
