Some details about Light microscope

Light Microscope 

               A conventional light microscope contains the following essential parts 

1. A light source: It may be sun's light (or) any other artificial light source.

a) A mirror: It serves as a reflector to make the light fall on the condenser lens.

b) A diaphragm: It controls the amount of light that could fall on the condenser lens. 

2. A condenser lens system: This system collects the light and focuses it on the specimen. 

3. Stage with clips: It is meant for keeping specimen/object. 

4. Objective lens: It is nearer to the object and magnifies the image of the specimen. 

5. An eye piece lens: I helps to further enlarge the image of the object and projects the image to the eye.

              The objective and eye piece lenses are mounted at the two ends of a hollow tube. This arrangement can be raised up or down by coarse and fine adjustment knobs. Magnification of the image can be increased or decreased by changing the objective and eye piece lenses.
