Essay On Microscopes

Before the twentieth century, the microscopes as it was publicly known today came with the development of technology and improved optics. The microscope can view small microorganisms in micrometers. Microscopes are the equipment used to see the tiny microorganisms by enlarging the image and adjust it. ‘Micro' can be defined as small while' scope' is defined as to look at. The Microorganism is measured in micrometers and only microscopes are able to view microorganisms. Micrometer (µm) also called a micron µ is equivalent to 0.0000001 m, and can be said 10 6 m while for the second unit the nanometer (NM) called a millimicron (mµ) and can be stated 10-9 m.

The first man makes and uses real microscopes is Antony Van Leeuwenhoek in the year 1632-1732,

However, he only explained a little explanation of their structure in the year 1683. After Leeuwenhoek is passing away no one can endure design and manufacture of microscopes flawlessly as him and because of that, the evaluation of microbiology slowed.

There are numerous developments in the optical microscope as Leeuwenhoek's time before the twentieth century. This microscope is Compound Light Microscope which it has more than one lens and it has own light source. Single eyepieces (ocular) with a compound Light Microscope are called monocular while two eyepieces are a binocular. The other name for compound light is a bright field microscope because it has a light source in its base.

The principal uses for bright field is to observe of numerous stained specimens and morphology of microorganism, to observe of motility and to measurement of size. Magnification is utility of making an object looked larger. To calculate the total magnification of specimen is an objective lens magnification multiply the ocular lens
