Optical microscopes utilize visible light and a system of lenses to magnify small samples that are usually un-seen to the bare eye. The optical microscope is the first, oldest and simples type of microscope (as opposed to the far more advanced electronic microscope).
Because of it’s compact dimensions, simplicity and relatively low price, the optical microscope is very popular, and may be seen in use in many areas of biology. Optical microscopes mostly magnify items for up to 1500 times. You can also ‘get best fluorescence microscope at http://www.einstinc.com/.
Today, the simple structure is in use only in the magnifying glass, hand lens and the loupe.
The more advances optical microscopes, and those that are popular today, are what’s called “compound optical microscopes”. These microscopes use a system of many lenses, so as to “compound” and multiply the magnification, and therefore maximize it. Look for confocal microscope via visiting http://www.einstinc.com/.
The two main lens systems in an optical microscope are the objective lens (near the examined object), and the eyepiece lens (up near the eye of the scientist). Modern optical microscopes use multiple lenses both in the objective part in addition to the eyepiece part.
The old optical microscopes also used a mirror to provide illumination below the object. The contemporary optical microscopes use a solid lamp to provide constant and powerful illumination.
