Microscope Parts & Specifications

• The Functions of a Microscope.
• Eyepiece Lens: the lens at the top that you look through, usually 10x or 15x power.
• Tube: Connects the eyepiece to the objective lenses.
• Arm: Supports the tube and connects it to the base.
• Base: The bottom of the microscope, used for support.

Head – This is also known as the body, it carries the optical parts in the upper part of the microscope. Base – It acts as microscopes support. It also carriers the microscopic illuminators. Arms – This is the part connecting the base and to the head and the eyepiece tube to the base of the microscope.

The three basic, structural components of a compound microscope are the head, base, and arm. *Head / Body – houses the optical parts in the upper part of the microscope.

1. Plug in the microscope.
2. Turn the microscope light on.
3. Place the stage as far away from the objective lenses as possible.
4. Rotate the revolving nosepiece until the lowest power objective lens clicks into place.
5. Looking at your stage from the side, place the specimen over the hole in the stage.

If your eyes are too close set or far apart for the intraocular distance to be adjusted properly, you will have to use your microscope as a monocular instrument (i.e. look through one eyepiece with one eye). If you do this, it is important to keep both eyes open in order to avoid eyestrain.

Answer: 1. First, the purpose of a microscope is to magnify a small object or to magnify the fine details of a larger object in order to examine minute specimens that cannot be seen by the naked eye.

A hand-lens, for example, might be labeled with 10x, meaning the lens magnifies the object to look ten times larger than the actual size. Compound microscopes use two or more lenses to magnify the specimen. The standard school microscope combines two lenses, the ocular and one objective lens, to magnify the object.

Total magnification = Objective magnification X ocular magnification. So for 10X objective and 10X ocular, Total magnification = 10 X 10 = 100X (this means that the image being viewed will appear to be 100 times its actual size). For a 40X objective and 10X ocular, Total magnification = 10 X 40 = 400X.

Lawrence Berkeley National Labs just turned on a $27 million electron microscope. Its ability to make images to a resolution of half the width of a hydrogen atom makes it the most powerful microscope in the world.
