When you hear the term inverted microscope, you probably think of observing samples from under a microscope. You probably get an image similar to a car mechanic fixing something under a vehicle. It is a funny image but this is not exactly the case when it comes to these kinds of microscopes. The only inverted parts of these tools are the source of light and the objectives that enable you to see the sample plane. Besides, a microscope that places the observer under the equipment will be ill-designed. Just imagine the risks of the specimen toppling and falling onto the observer.

What Does an Inverted Microscope Look Like?

An inverted microscope has the light source and condenser on the top. They point down to the stage where the specimen is placed. The objectives and turret are under the stage. They point up to the bottom of the plane. Just like upright microscopes, the specimen is placed on top of the stage. The binoculars are not pointing up, as one would imagine, but pointing down.

How Does an Inverted Microscope Help in Living Cells Studies

Results of living cells studies should be derived from observations of live cells. This can be done with a typical upright light microscope. The method involves taking a small sample, placing it on glass slide, covering it with a slip, and keeping it moist with water. This is effective and has been used countless of times. However, there are some pitfalls to this method. First of all, by taking a sample from the culture, you are most likely altering the natural processes of the cells. Moreover, the cover slip will put pressure on the specimen, thus altering its processes, too. The water that you use to replenish the sample can also affect its life. Obviously, using an upright light microscope is not ideal for a prolonged observation of living cells.

But if you utilize an inverted microscope, the chances of observing them for a long period of time increases. This is possible for various reasons. One is that you will not have to remove a sample to be placed in a glass slide. The design of the microscope allows for bigger objects to be placed on the sample plane. For instance, if your sample is in a petri dish, you can place it on top of the stage. This way, there will be no pressure on your specimen and the environment will not be altered with constant water replenishment.

Since living cells constantly change from one form to another, being able to observe them for a longer period of time without killing them is essential if you are to study them. Sure these microscopes are a little bit expensive but if living cells study is your field, it is wise to invest in one. The results of your studies will be a whole lot better and you will not regret ever buying it. There are also aspects where the microscope can still be improved but you cannot deny the fact that in most cases, using this microscope is better than using a light microscope or an electron microscope.

Microscopes come in many forms and types. Gone are the days when the only terms related to the microscope are the electron and the compound microscopes. Today, there are numerous kinds and you don’t even know what each is really used for. You can’t even differentiate one type from another.

To clear that clutter on your mind, let’s get a few things straight.

First, the modern microscope can be classified according to compound or stereo. The compound microscope uses only one eye-piece (that cylindrical part of the microscope that you put your eyes on to see the specimen being examined). On the other hand, the stereo microscope uses two optical paths and has the ability to give you a 3D image. It is for this reason that this kind of modern microscope is very popular in surgery and in dissecting objects and even machine tools.

Second, there are two frame types of the modern microscope: the upright microscope and the inverted microscope. For you to have a clearer understanding on the difference of the two, you must be familiar with the major parts of the microscope first.

* The Illumination system – this refers to the group of parts that gives lighting to the specimen. This group includes the lamp, the condenser, the diaphragms (or pinhole apertures) and the rheostat, among others.

* The Stage – this is where the specimen rests. Usually, the specimen is held in place and moved with the use of clips and a micromanipulator, respectively.

* The Lens system- these are the group of parts responsible in forming the image. This includes the eyepiece, objective lenses, tube and the nosepiece (the mount that holds several objective lenses).

To distinguish an upright from an inverted microscope, you only need to remember the placement of the three major microscope parts mentioned above. The upright microscope is your standard view of a microscope: on top is the lens system, followed by the stage, and then the illumination system. The inverted microscope, on the other hand, has the reverse sequence. You have the illumination system on top, then the stage, followed by the lens system.

Does an inverted microscope make sense? At the outset, the idea might seem ridiculous. But upon careful consideration, you’d realize how useful an inverted microscope is.

This kind of frame is very useful in examining a specimen that’s either too large or too heavy. Yes, an inverted microscope would come in handy if you want to study cells in suspension. This is because the lenses are closer to the bottom of the specimen – where the cells are. Thus, it makes more sense to make use of an inverted microscope rather than an upright microscope in this scenario.

Microscopes – just like cameras – use accessories too. Among the widely used accessories are: the Epi-fluorescent attachment kit, a mechanical case, or even a microscope case. These make your microscope become more powerful (just when you think they could not get any more powerful, huh?).

So there you are, a little clarification about the many terms related to the microscope. To review, the modern microscope can be classified as either stereo or compound. But in relation to frame types, only two words must come to mind: upright and inverted. Easy enough, right?

What do you know about inverted microscopes?

Inverteds (as they are called) got their name because the recognized standard – the upright microscope – works in a specific way, and is the most easily recognized orientation of a microscope. Upright microscopes look down at specimens with light source below it. These are the types of microscopes usually used by medical technologies doing your blood work; inverted ones, on the other hand, look up the specimen with light sources above the specimen.

Although the equipment was first introduced in the 19th century, it saw use in the observation of marine life only during the first years of the 20th century. During World War II, the inverted microscope was used to analyze solid, heavy metals like iron and steel. These days, inverteds are useful in many types of research that use large, heavy or otherwise bulky samples requiring a wide berth of geometry.

Aquatic Research and Sciences

Although the ecology in deep seas can be recreated for observation of a small bowl or a miniature aquarium, the container holding the specimen requires a relatively wide staging. Additionally, aquatic live and living organisms are prone to gravity and tend to settle down the base of the container. This makes it ideal to place the sample or its container above to allow for more flexibility and to be able to conduct observations in more natural circumstances.

Modern Microscopes

By now, you’d have surmised that inverteds are useful in several fields, particularly in research observations. Besides aquatic and materials research, inverteds are also useful in observing tissue culture on petri dishes — a common method used in biological sciences and medicines research. Modern inverted microscopes however, are designed for flexibility, with the user in mind.

Today, most modern microscopes are able to multi-task, with the whole ensemble being a collection of interchangeable parts that can be fitted together to serve a purpose. Manufacturers have worked hard and are working hard to meet the demands of the various sectors and users of microscopes. They are also integrating microscopy techniques to create separable modules.

In this day and age, the more modular a microscope is, the more economical it is. Manufacturers make a wide range of modules to suit many purposes across disciplines, users, and even across different microscopy techniques. So, if you find an inverted microscope with an epi-flourescent attachment, don’t be surprised. That’s evolution at work.

Technology Integration

Besides the modularization of inverted microscopes, new designs include internal light sources that are below or parallel to the specimen. Most viewing and recording controls are still below the sample. This new design allows you to put specimens directly on top of the microscope. This, in turn, allows you to manipulate sample placement in a wide geometry of choices for total flexibility.

More advanced models integrate video capabilities for specimen scanning and direct digital or analog data recording. This is very useful in various laboratories that require fast, data analysis. Often, these video microscopes are integrated into the laboratories digital or automated systems for sample analysis.
