A microscope is derived from Greek word mikros which mean small or to look. Microscope is an instrument which is used to see the object which is small through the naked eye. The first microscope was developed in the year 1590 but the original inventor is not yet known. Ever since the invention of Light Microscope made in 1500, it has helped in enhancing our knowledge in basic biology, medical diagnostics, material science and bio medical research. The light microscope has the ability to magnify the object up to 1,000 times bigger, revealing microscopic details. Light microscope has evolved far before the first microscope. Light microscope has special techniques and optics which is developed to reveal the biochemistry and structure of living cell. Microscope has entered the digital age using the digital cameras to capture the images. But the basic principle of advanced microscopes is same as the microscope you would have used in your first biology class. The microscope has allowed immediate study of the effects of the space environment. The ability to use the light microscope has enabled the scientist to study the date unaffected Polarising microscope is also known as petro graphic or geographic microscope. This microscope was developed in the year 1970. It is conventional microscope which has additional features that will allow you to observe the object in the polarized light. The light source of this microscope is polarized filter so that the light which is supply must be linearly polarized. In other words the light waves move in given direction rather than moving in all the direction. This type of microscope is used to examining rocks and mineral. It is also used in medical laboratory in examining the urine crystal. It is also helpful in the field like biochemistry research, geological engineering and in petroleum industry. It helps in knowing the characteristic and feature of different types of stones. A simple polarizing microscope can be easily made by adding the cheap polarizing filter to the standard biological microscope, with one filter next to condenser and second one inserted next to head or eyepiece.
