The composition light microscope is one of the most ordinarily used types of microscope. Among its many uses is the science classroom, where they are an affordable and easy to use instrument for studying biology and chemistry. The instrument traces back generations, but recently has evolved into a very modern instrument.
Only a few decades ago, you could find the microscope in just two basic types. There was the monocular composition microscope and the binocular compound. That is, the composition light microscope came with either one or two viewing units. With the monocular compound, there was a singular eyepiece and so you looked at your specimen with just one eye. This is still what many citizen envision when they hear the word "microscope." Then there's the binocular model which, naturally, resembles a pair of binoculars. That's because there are a pair of viewing units, one for each eye. Today, there are few if any monocular composition microscopes made. The new thorough is the binocular.

However, even more recent times have introduced to us a newer standard. This is the trinocular composition microscope. The "tri" signifies a third viewing port. This makes it a not-as-common spin-off of the binocular compound.
The function of the trinocular microscope is a bit different, since most citizen only have two eyes. The third eyepiece, then, is for use by a second person. It comes in handy in a consolidate of situations. First, if two citizen need to consult together over the same specimen, they are able to look at it at the same time. A second and more tasteless use of the trinocular is to allow a science educator to see the same thing that his learner sees under the microscope. A third good use for it is to take pictures of the specimen with a camera placed over the third eyepiece. Each of the microscope parts functions in harmony, allowing the camera to see what the person's eye sees.
The composition light microscope, as suggested earlier, is powerful due to its pair of optic parts. Let's discuss these and how each of them is used.
1. First of these parts are the objective lenses on the scope. These lenses sit right above the specimen, collecting the light emitted by the specimen. The typical composition microscope has 3, 4 or 5 objective lenses. Each of these will offer a slightly different level of magnification. These objective lenses are held together by the nose piece. As this nose piece is notated, the magnification is altered by a different objective lens.
2) The eyepiece is the second major part. This is the part that your eye looks directly straight through to see the specimen. It's a cylinder shape and contains a lens. The eyepiece is also called the microscope ocular.
As these two major parts work together, there are is a huge range in magnification available. In fact, if it fits on the microscope, there is almost unquestionably a magnification level that will bring it to life for you. It's virtually unlimited in the viewing inherent it offers you.
The composition scope has some other foremost parts, too, like the condenser. The condenser is one of the more brittle but foremost parts. There are other foremost parts to the microscope, such as the condenser. A diagram of the parts condenser is helpful to make sure it stays in good condition. Do a Google or Yahoo hunt for more information.
Costs for your microscope might vary, but usually they will run in the range of 0 to 0 for a modern composition light microscope. Expect to pay the higher price especially for a trinocular microscope. You can, of course, find them cheaper used, but make sure to survey the lenses closely to make sure there are no scratches or cracks. There's a lot of power in a composition light microscope, as long as you don't compromise on quality.
