Compound microscopes are tools which allow the human eye to view tiny objects that would otherwise not be observable. Becoming familiar with the functional parts and terms of the compound microscope is a great way to increase you understanding. See below for these parts and terms for a compound microscope.

It may sound strange, but the magnifier with the highest power isn't always the best choice. The human eye has an optimal viewing distance: the closer we hold an object to our eyes, the more of its detail we can theoretically see, but it will be out of focus. That's where the magnifying glass comes in. A magnifier with a 2X power, for example, enlarges an object and lets us see it as though it were two times closer to our eyes, but the object remains in focus. Does that mean that a magnifier offering 20X power is ten times more useful than our 2X magnifier? Not necessarily. There are limits to the practicality of a high-powered magnifying glass, because of the way that magnification, focal length and field of view work together.

There are tons of cheap inferior magnifying glasses out there claiming 20X, 30X, and even 45X magnifications, yet they sell for less than $10. These are false claims as any magnifier over 20X magnification will have such a small field of vision that they are no longer considered magnifiers, but rather loupes . Higher quality lenses with high magnifications are also more difficult to produce, consequently they tend to be more expensive.

2X and 3X Lenses are the most popular choices for an average user as it offers higher magnification without sacrificing the field of vision (diameter of the lens). On the other hand, a 10X magnifier will reduce the field of vision significantly, but it will give you a closer look at tiny rocks, crystals, minerals, microfossils, etc.

The focal length of a magnifier is the distance from its lens to the object being viewed, when the object is in focus. The power and focal length of a magnifying glass are actually inversely related. In other words, the higher the magnification, the shorter a magnifier’s working distance is, and vice versa. Having sufficient room to manoeuver beneath the lens is an important consideration when your hobby or project requires the use of tools, and it’s one of the reasons why a higher magnification isn’t always the better choice.

First and foremost, you should decide what purpose your magnifying glass is going to serve. It’s far better to let the project determine the magnifier required, than to try and turn a single magnifying glass into a one-size-fits-all tool:

Essentially a compound microscope is a high magnification microscope that uses 2 lenses to compound (multiply) the level of magnification. The first lens is referred to as the objective lens and typically has a 4x, 10x, 40x or 100 magnification ability). The second lens is known as the eyepiece lens. This lens compounds or multiplies the magnification of the objective lens by another 10x resulting in a total magnification of 40x, 100x, 400x and 1000x.In short, a compound microscope is a high power microscope that uses two lenses to increase magnification of tiny objects that would otherwise not be observable.

Always check the lens for scratches. Place the magnifying glass on a piece of white paper and see if the lens adds any color of its own. Then pick it up and examine other objects, specifically objects with more colors.

The field of view refers to the size of the area that's in focus when viewed through a magnifier’s lens. In much the same way that focal length is inversely related to magnification, so too is the field of view. The higher the power of a magnifying glass, the smaller its field of view will be. That means you'll be able to see more detail with a higher magnification, but only across a relatively small area. Generally speaking, a 2-3X magnifier offering a larger field of view is better for scanning activities like reading, while the smaller field associated with a higher magnification would be more appropriate for the inspection of fine detail.

The most common laboratory scopes, the compound microscope (also referred to as light or compact microscope) and the stereomicroscope (also referred to as a dissecting microscope), have different uses.Compound microscopes have a glass lens contained in the ocular (the eyepiece typically has 10X magnification), and a lens in each objective (4X, 10X, 40X, and 100X are the common objectives found in microscopes used in education, although not all microscopes have a 100X objective). Magnification is simply the ratio of the object size viewed through the lens to that of the actual size of the object.
