Introduction

The light microscope which is often called the symbol of research and scientific discovery, which has evolved over last 350years from Anatole van Leeuwenhoek’s simple magnifier to the more sophisticated instrument of today.
Microscope is a device which is used to magnify the smallest entities which is not visible from our naked eye. Using the light microscope the objects can be enlarged or magnified with a convex lens that bends light rays by refraction. The visibility of the microscope depends on the resolution.
Light microscope is mainly used in the lab activities. This instrument has two lenses and various knobs which is used to focus the image. And also this instruments should be carefully maintained to prevent any damage to the main parts such as the
