Important Parts And Usage of Compound Microscope

A compound microscope may serve the purposes of magnifying small objects in different environments. From school laboratories to forensic and scientific research labs, it acts as one of the most useful tools. In fact, many curious people buy them to pursue the interesting hobbies of collecting different kinds of specimen from forests ad beaches.

Microscopes can be best used by understanding their important parts. The structural parts of a microscope include head, arm and base. Lenses are obviously among the most important parts of these tools. Eyepiece is the lens through which the user views the specimen. Objective lenses magnify the specimens so that the resultant images are clearly visible. A compound microscope may have up to 5 objective lenses, each having different magnifying ability.

There are many parts of a microscope that help in making different types of adjustments. Those with two eyepieces have diopter adjustment which helps in changing the focus from one eyepiece to another. Coarse and fine adjustments are two important components in the form of knobs that are attached together. While the former helps in adjusting the general focus of the microscope, the latter brings the specimen into fine focus for better detailing.

The light source of a compound microscope is called illuminator. Condenser is another worthwhile part which consists of iris diaphragm to adjust the diameter of the light beam from the illuminator. Nosepiece houses multiple objective lenses and stage is used to place the slide containing the specimen. The stage has an aperture that allows the light from the illuminator to illuminate the specimen.

Using a microscope involves adjusting different types of adjustment components. First of all, prepare a slide and place it on the stage. Switch on the illuminator and select the objective lens you wish to use by spinning the nosepiece. Use the coarse and fine adjustment knobs to set the focus by moving the mechanical stage. It is important to ensure that the slide does not have contact with the lens. Look through the eyepiece and adjust the brightness of the light as per your convenience. Enjoy the magnified image of the specimen through the compound microscope.
