The Importance of Using Triple Viewing Teaching Microscope

There are special types of microscopes that can accommodate three people to view one sample at the same time. These microscopes are primarily used for teaching and instructional purposes. Learn what these microscopes are made of and their most salient features.

When teaching biology or health-related subjects, there are certain types of microscopes built that is specifically built for the job. Teaching about a microscopic organisms is not really easy, especially if you need to show something in particular to students.

But the need to have three people look through a single sample at the same time becomes possible with the triple viewing teaching microscope. These microscopes are professional grade microscopes equipped with triple heads that are primarily used for teaching and training purposes. These microscopes usually have a pair of binocular eye piece and two monocular eye pieces. The two monocular eye pieces are positioned on both ends while the binocular is right at the center.

Because of this remarkable feature, two students and a teacher can possibly look through a sample simultaneously. These microscopes are also equipped with high power objectives that are capable of producing bright and clear images of specimens. For three people to view a sample, the eye pieces are connected to a rectangular bar from which the objectives are also attached. The microscope only has one set of objective lenses and a stage. The rectangular bar from where the eye pieces are connected to are equipped with the necessary mirrors and view tunnels so that the images is transmitted from to the center and the two sides.

A triple viewing teaching microscope is usually equipped with four objective lenses. The lenses are capable of 4 x, 10 x, 40 x, and 100 x magnification powers. The three eye piece lenses, on the other hand, works following a standard 10 x magnification power. Together, the images produces can be enlarged to a 40 x, 100 x, 400 x, and 1000 x magnification power respectively. The 100x objective is an oil immersion type of a lens. This means that before the sample can be magnified to as much as 1000x, a special type of mineral oil is needed to be applied first.

For ease of viewing, the heads of the triple viewing teaching microscope are inclined at a 45 degree angle. They can also be rotated at a full 360 degree angle. The binocular head has a 55 to 75 millimeters interpupilary distance adjustment as well. All oculars of the scopes, on the other hand, have diopter adjustments that are used for adjusting the focus of training stations.

Triple viewing teaching microscopes are also equipped with a substage condenser and a corresponding movement knob in order to adjust it. It also has an iris diaphragm and a swing-out holder of filters. For a more precise alignment of the microscope’s light path, a condenser configuration screw sockets are put in place. These microscopes also has a rack and pinion gears that are made of quality steel to achieve better and easier condenser movements.

The most common illumination system that a triple viewing teaching microscope uses is a tungsten halogen lamp that works on a transmitted base lighting system. The light has a variable intensity of 20 watts, which means it can be adjusted for a better image contrast when viewing the specimen.

The triple viewing teaching microscope’s stage is usually large and mechanical. It is graduated for easy measurement and can be moved up or down, or in a longitudinal X-Y axis directions. Its stage usually measures 132 millimeters by 141millimeters in size. To move the stage following the coaxial X-Y planes, the knobs for it can be adjusted accordingly.

For focusing the device, the coaxial coarse and fine focus adjustment knobs fitted on the two sides of the microscopes can be used. So that the both the objectives and the specimens are protected, these knobs are equipped with an adjustable lock stop in order to limit the adjustments. The coarse focusing knob is normally tension adjustable.

A triple viewing teaching microscope is usually 480 millimeters tall. The whole instrument weights 20 and a half pounds, which is very ideal because it is not too heavy it can’t be moved around, or too light that it can pass more as a toy than a functional device. The package typically includes a bottle of mineral immersion oil for the 100x objective, an extra bulb, and a fuse.

These are the common features of a triple viewing teaching microscope. If you need to supply your school with microscopes, these are the best options. It is the better instructional microscope that can be bought at a very affordable price.
