Many specimens are microscopic. Hence to see them, they have to be enlarged using a microscope. Other times, the parts of the specimen has to be enlarged to see and study them clearly. Hence we need to magnify the specimen. This is accomplished by using the optical system in a microscope.

Magnification is the apparent enlargement of an object by an optical instrument. In all cases, the magnification of the image does not change the perspective of the image.
