TECHNICAL DESCRIPTION Of Optical Microscope
TECHNICAL DESCRIPTION
OPTICAL MICROSCOPE
Introduction
The optical microscope has been a standard tool in life science as well as material science for more than one and a half centuries now. The optical microscope widely use in the field of cell biology, microbiology, biotechnology, pharmacology, forensic and medical diagnosis especially when dealing with tissue fragments. It is a type of microscope which uses visible light and a system of lenses to magnify images of small samples. In other words, Optical microscope is a technical device which is used for visualizing structures that are too small to see with the unaided eye. The LED of microscope features a long service life of 20,000 hours and offers low power consumption. The overall weight of an typical microscope is 6kg. The overall height of an optical microscope is 384.5mm and 238mm wide, compact enough to be stored in a typical classroom cabinet. There are 3 main parts of the microscope such as illuminating parts, magnifying parts and mechanical parts. The sub-parts in illuminating parts are electric lamp and iris diaphragm while the sub-parts of magnifying parts are eyepiece and objective lens. The mechanical parts consist of most sub-parts among these three such as barrel, arm, stage, coarse focus knob, fine focus knob and base.

Illuminating Parts:
Electric Lamp
The illuminating parts such as electric lamp and iris diaphragm are used to provide light. The 20 watt electric lamp is the light source for the microscope. Usually optical microscope utilizes a built-in halogen bulb for bright illumination and to prevent eyestrain. It is located underneath the stage. It has maximum overall diameter of 1.31 inches. The brightness of the lamp can be adjusted with the dimmer.
Iris Diaphragm
Iris Diaphragm is a rotating disk under the stage. It is made up of usually a series of metal plates. An iris diaphragm is
