How does the lens of a light microscope work

Light from a mirror is reflected up through the specimen, or object to be viewed, into the powerful objective lens, which produces the first magnification. The image produced by the objective lens is then magnified again by the eyepiece lens, which acts as a simple magnifying glass.

Reflection and magnification

Explanation:

A light microscope reflects and enlarges an image from a specimen. The specimen can be anything. It can be a plant cell, animal cell or in most advanced cases, small organisms such as viruses.

The light microscope depends on light. The light can be artificial or electric light. The light is shot through the specimen. It is reflected on the primary lenses. This light is reflected and magnified on the secondary lenses. This produces a magnified image.
