How A Compound Light Microscope Works :: Optical Microscope

The compound microscope, also known as the compound light microscope, belongs to the original family of optical microscopes for science, research and biological studies.

Earlier styles of compound microscopes relyed on a focused mirror reflected light to illuminate the subject from the underneath as opposed to the more modern active illumination source of an electric light bulb or similar were referred to as a compound light microscope.

The common compound microscope in any of it's styles performs the basic duty of magnifying the subject for further investigation and detailed observation.

How The Compound Microscope Works

The compound works by adding magnifications inline with one-another. The effect of multiplied magnification enables this type of compound microscope to offer more powerful magnification - typically 40X to 1000X in the standard single eyepiece minocular and 40X to 2000X in dual eyepiece biological binocular compound microscope. This is the most recognisable of all microscope types with varying magnifications (lenses) mounted on a spindle for easy rotation and selection - though some require replacement of a single lens.

Early days of microscopy

Corke Cells

Drawing of cork cells published by Robert Hooke in 1665.

In the early days of microscopy an English scientist, Robert Hooke, decided to examine thin slices of plant material. He chose cork as one of his examples.

Looking down the microscope, he was struck by the regular appearance of the structure, and in 1665 he wrote a book containing the diagram shown in Figure 1.2. If you examine the diagram you will see the 'pore-like' regular structures that Hooke called cells'.

Each cell appeared to be an empty box surrounded by a wall. Hooke had discovered and described, without realising it, the fundamental unit of all living things.

Although we now know that the cells of cork are dead, further observations of cells in living materials were made by Hooke and other scientists. However, it was not until almost 200 years later that a general cell theory emerged from the work of two German scientists.

In 1838 Schleiden, a botanist, suggested that all plants are made of cells, and a year later Schwann, a zoologist, suggested the same for animals. The cell theory states that the basic unit of structure and function of all living organisms is the cell.

Now, over 170 years later, this idea is one of the most familiar and important theories in biology. To it has been added Virchows theory of 1855 that all cells arise from pre-existing cells by cell division.
