Types Of Lenses And Features Of Compound Microscopes

Compound microscopes are among the most common types of devices which are found in most of the laboratories and classrooms. It is known to be one of the most fundamental tools found in science laboratories. These devices basically include a tube with two convex lenses.

Compound microscopes are used for several applications. It is mainly used to conduct researches on cells, bacteria, molecules and so forth. This unique device was invented by Zacharias Janssen in the year 1590. The designs of this device were later on upgraded with various innovative techniques.

This device includes a series of magnifying lenses. There are two types of lenses which are included in this device. The objective lens and the eyepiece are the two types of lenses in these devices. The eyepiece is the lens which is closest to the eyes. The objective lenses are a series of lenses which are close to the object. There are three to four objective lenses in most of the compound microscopes.

These microscopes can be monocular, binocular or trinocular based on the number of eye pieces. Apart from the lenses, there are other parts which are included in these devices.

The arm which connects the base of the device and its tube is another part of the microscope. The objective lens is connected to the eyepiece with the tube. The objective lens is held by the nosepiece which is basically a rotating piece. This rotating piece can be adjusted for better viewing process.

The specimen is lighted with a light source which reflects light through the bottom of the device. The slide is held by a flat platform or a stage that is located beneath the objective lens. This stage can be adjusted for better viewing purposes.

Compound microscopes can be bought from various reputed online stores at affordable price rates. There are different types of microscope devices which can be ordered through online portals. Some of the manufacturers also offer customized devices for unique purposes. As there are a huge variety of devices made available through online stores, it is important to know how to choose these devices based on its specifications.

Compound Microscope Versus Stereo Microscope

There are basically two types of microscopes which include the compound and the stereo microscope. Both these devices vary on the basis of a number of factors. Nevertheless, both these instruments depend on the manipulation of optical light for visual amplification. Microscopes are chosen according to individual applications and different instruments have different set of features.

The structural elements of these two types of microscopes are more or less identical. Both these devices include a head or body which holds the optical units. It also includes an arm which joins the head and the base of the apparatus. The base holds the entire apparatus and the illuminator.

Common Differences:

The compound microscope function with three to five lenses. It is available in single and double eye-pieces. The specimens can be viewed from atop through a single vertical view. A single optical path system is followed for magnification of the objects. In some of the compound microscopes, a camera can be mounted on the third tube.

Stereo Microscope

Stereo Microscope

The magnifying lenses are mounted on a nosepiece that can be rotated easily. The compound microscopes are generally used to view small objects such as bacterium and cells. The device offers two dimensional images.

The stereo microscope is another type of microscope which is also known as the dissecting microscope. It has two similar magnification eye pieces which can be used to examine the specimens. It is quite similar to two compound microscopes which are set independently. These microscopes are available with have extra zooming capabilities. It is widely used by biologists to perform dissections, paleontologists to clean and examine fossils and so forth.

These microscopes also include built in light sources from below and above. However, there are some models which have no light sources at all. The power of magnification is less in stereo microscopes although it provides 3D viewing powers. It is also relatively inexpensive compared to the other types of devices.

Compound microscopes are used in clinical laboratories, educational institutions, biology and various medical fields.

Stereo microscopes are generally used for examination of documents, hair grafting, metallurgy, geology, dentistry and so forth.

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.

The compound microscopes are used in various fields for various purposes. Student microscopes are easily available and are quite inexpensive where as the professional compound microscopes are quite expensive.

Basic Features of Compound Microscopes

One of the most important components of a microscope includes the ocular lens which is included in the eye piece of the microscope. The ocular lens is mainly used to view and magnify the objects for close examination. The objective lens is another component found in compound microscopes. These lenses have around three to four lenses attached to the nose piece that can be rotated easily. All these lenses have different magnifying strength.

The adjustable knobs or the magnification controls are other significant parts of a compound microscope. There are two types of knobs for these microscopes. These knobs are mainly used to adjust the focus of the specimen to be examined and the height of the stage.

All microscopes require certain amount of illumination to view the specimens. The light source provides ample amount of light through the diaphragm. The light passes through the lens and the specimen to be examined. Today compound microscopes can also be customized according to individual requirements.
