With the help of the appropriate microscope, you may take a more in-depth look at your surroundings and acquire a whole new viewpoint of the universe. Really, they aren’t just scientific equipment, but also a delightful way to discover the world around you in novel ways.
For instance, you may have seen that the phrases “stereo” and “compound” are used very often. Of course, the vast majority of readers are already familiar with these phrases; however, when applied to microscopes, they take on a whole new meaning. Compound and stereo microscopes are the two types of scopes that are used the most often. Which one of them do you need, then? Read our guide to find out the differences between a stereo microscope and a compound microscope.
When Hans and Zacharias Janssen, a father and son duo from the Netherlands, were working on their invention of the first compound microscope in the late 16th century, they made the ground-breaking discovery that things on the other end of a tube might be magnified by placing a lens at both the top and bottom of the tube and then looking through it. This led to the invention of the first compound microscope. With its two sets of lenses, many eyepieces, and different focal lengths, the modern compound microscope can magnify things more than was possible in the past.
The image produced by a compound microscope is two-dimensional, and the magnification can range anywhere from 40 to 1000 times the original size. Microscopes come in a broad variety of features and prices and are used to examine extremely minute samples, usually placed on a slide, that could never be recognized or seen by the human eye. This has had a profound impact on our understanding of science and medicine.
Usage of a Compound Microscope
Compound microscopes are superior to stereo microscopes in terms of optical resolution and are thus the tool of choice when studying or inspecting tiny objects at extremely high magnification, such as bacteria, plant cells, algae, protozoa, animal cells, chromosomes, and thin slices of organs or tissues. For ultrathin samples that can be seen through, their tiny working distance of 0.14 to 4 mm is perfect.
However, for examining dissections or any other opaque, three-dimensional objects, compound microscopes are not suggested . Viruses, atoms, and molecules can only be seen through the lens of an electron microscope, so you can’t use a compound microscope to look at them.
Pros of Compound Microscope
The great magnification offered by these microscopes makes it possible to examine specimens at the level of individual cells. They typically have a single LED light and may be plugged into an electrical socket, eliminating the need for batteries. Additionally, they offer the accuracy necessary for professional competence while retaining an intuitive design that makes them simple to use for those with less expertise. The rotating knob allows you to alter the distance between the lens and your subject, and the form of the head makes switching magnifications a breeze.
Cons of Compound Microscopes
Unlike stereomicroscopes, which can offer a three-dimensional picture of an item, compound microscopes can only produce a two-dimensional image, making them inappropriate for use with bigger specimens like rocks, jewels, or other similar things. In addition, in order for them to function correctly, they have to be used on a surface that is absolutely flat, and they frequently need glass slides.
In the early 1890s, an American scientist and instrument builder by the name of Horatio S. Greenough invented the first stereo microscope. The notion that it has distinct objective lenses and eyepieces, which ultimately results in two different optical channels for each eye, is the primary innovation that distinguishes it from a compound microscope. This type of microscope is also known as the dissecting microscope due to the fact that the slightly angled views to the left and right eyes create a three-dimensional visual.
Nowadays, a stereo microscope can magnify objects 10–40 times and can examine samples too large to fit on a microscope slide. When linked to computers and LED displays, they can show far more extensive amounts of data, information, and visual graphics.
Usage of Stereo Microscopes
Examination of opaque specimens in three dimensions can be accomplished with the use of stereo microscopes. Insects, plant life, diamonds, jewellery, and electrical parts are some examples of objects that can be examined most clearly with a stereo microscope. This is because stereo microscopes have a larger working distance than other types of microscopes. They are therefore widely used in both scientific and industrial research facilities.
Pros of Stereo Microscopes
More of your material can fit in the stereo microscope’s field of view, so you can examine things like computer chips, flowers, and woven textiles. Most of the time, slides are not necessary, which results in their being less delicate components and accessories that need to be purchased, stored, and transported. A stereo microscope is the best beginner microscope. It also gives a three-dimensional perspective, allowing the user to see the observed specimens from a variety of angles and points of view. The viewfinder is angled at a 45-degree inclination, making it simple to see through and reducing the amount of pressure placed on the neck.
Cons of Stereo Microscopes
Most stereo microscopes require a power supply of some kind, whether it be a battery or a plug-in outlet. The lack of magnification means that only bigger specimens may be examined with them. Not only is this sort of microscope cumbersome to keep and move, but it also lacks the resolution necessary to examine objects at the cellular level. It’s important to have some prior expertise with using a stereo microscope, as well as some time to get used to using one.
