The Exciting World Seen Through a Fluorescent Microscope

If Anthony Van Leeuwenhoek were alive today, he would eagerly trade his one-lens microscope for a mighty powerful  laboratory fluorescence microscope to observe the strange bugs and critters in color. If he was excited about his observations with a 'crude' microscope, wouldn't he be titillated with the modern microscope?
A World of Wonders
To non-scientific minds, a microscope is a microscope and that's that. It's just piece of equipment one had to grapple with during elementary and high school. But if they take the time to explore and experience the life forms revealed through the lenses of a fluorescence microscope they will be surely amazed to discover invisible life forms of all stripes and colors, unseen by the bare human eye.
The fluorescence microscope is a perfect microscopic observation tool because it produces a 'larger-than-life' image of microorganisms and in color to boot, a thing unheard of in Leuwenhoek's lifetime. Through the ultra-powerful lenses of this microscope, one can observe different microorganisms - bacteria, viruses, and fungus as they pulsate with life and move in their own curious ways.
Again through the lenses, mesmerizing action like the splitting of human, animal, and plant cells can be observed. Diseased body cells can be probed up close and their behavior noted and compared with healthy cells, which to scientific minds unlock the secrets to finding the cure for dread diseases. Your astonished eyes can see the contours of the tissues and distinguish them because different tissues emit different luminous colors of greens, blues, reds, violets, and oranges.
Secrets of the Microscope Revealed
The fluorescence microscope does not use the common absorption and light reflection techniques to give a good magnified view of the invisible specimens. Here, light is used to excite the specimens causing them to emit light in longer wavelengths. This ability to give off luminous light is known as fluorescence. The more intense the light used, the longer the wave length of the light coming from the specimen. You can compare the image to digitally clear color pictures.
The light technique is the Kohler illumination, an invention all scientists and hobbyists have waited for. The Kohler illumination solved the problem of hazy images of specimens because it gives superior lighting, paving the way for the concise recording of microbiological observations.
However in this world of microscopic technology, nothing is perfect. The microscope has limited resolution limit - this is true with all microscopes. To get a concise image viewing, high powered cameras are necessary to boost the optical function of microscopes. A CCD camera can increase magnification or the size of the specimen for monitor display.
Grasp Nature's Hidden Secrets
The technical information about the fluorescent microscopes will not be appreciated by non-scientific minds; but these minds can only be humbled by the wonderful scenes that unfold beyond the lenses of the microscope. The fascinating patterns of skin tissues and unusual shapes of rock specimens, and semi-conductors are enhanced by splotches of luminous colors that imitate art.
The spectral invisible life forms and the stuff man take for granted such as the microscopic details of his body parts are magnified a 'thousand-fold' by the fluorescence microscopes . So you thought you have seen it all!

The Compound Light Microscope - How to Choose the Best Microscope for Your Application

The process of choosing a new compound light microscope requires a number of considerations. Two primary things of importance are where and how you plan on using the microscope. Therefore, a researcher or scientist in most cases will have more needs and requirements compared to a hobbyist when purchasing a microscope. Another consideration to make is quality.
As mentioned before, one of the primary factors that should determine the type of compound light microscope you buy is your primary purpose for buying the confocal fluorescence microscope and whether it is for a hobby or work. Largely, your planned application remains important since you want to ensure the microscope will perform the way that you need it to.
For instance, a high school biology teacher would not need the same type of technologically advanced equipment as would a researcher working in the biomedical field, or technicians in the laboratory/clinical setting.
Furthermore, you need to make sure the compound light microscope you plan to buy will have the type of accessories you will need. Ultimately, every type of microscope has a large range of different options. All of them differ in the type of accessories they are compatible with, in addition to viewing power and other options.
Finding the Best Compound Light microscopes for beginners - How to Evaluate Quality
The body construction, illumination, and lens quality are all important factors to consider. In addition, comfort is vital and microscopes today are built with user ergonomics in mind.
Light microscopy applications are also important, whether you are needing polarized light, dark field or perhaps phase contrast. Microscopes can come with these additional modules already built in or for similar expense you may find a module that is acceptable to use with a used microscope, lessening the expense further.
Personally evaluating your own research needs is the best way to find the compound light microscope that sufficiently suits your needs. However, this is very time consuming process. Of course, you can find a lot of information on the Internet within a small amount of time, but the sites you may stumble upon are not always going to contain the type of information that you are looking for.
In most cases, if you are trying to compare microscopes, you are going to want to find a site that dedicates itself to researching the different types of microscopes that are out there, new and used, as well as having thorough explanations on what a particular type of microscope is and what it is used for.
A good review site on compound laboratory microscopes will give you information on features, specifications, performance, comfort, in addition to ease of use and more. Furthermore, they will help you to compare and find the best microscope from some of the latest technologies.
Even if you are a professional in the field, you just might take away something new from serious research done on the different microscopes available. Ultimately, in depth reviews are one of the best ways to help you determine which compound light microscope is right for you. Primarily, a dedicated comparison site does all the research so you do not have to. Some of the main advantages this offers is saving you time by giving you access to the latest information available.

Monocular Compound Microscope

Remember middle school science class? That was during the time most people found science the most fun and fascinating. You got introduced to the microscope and got to look at cool thing up under it and see it in great magnitude. You can take an item that you see everyday and place it under the interrogation table as I like to jokingly call it and see a thousand different things there that the naked eye will never catch. The faint at heart didn't like to look as much since some things can be a little too much to have such a close look at. But to those who love the science of discovery, bizarre, and oddity that can be a cool dream come true. How are we able to see such contrast? What are these monocular microscopes that allow us the pleasure of exploring? What are monocular compound microscopes? Thanks to the science world and scientist altogether we are able to examine and pick apart objects to get a better understanding of the world around us. We get to look at microscopic organisms and dissect into unknown and unfamiliar territories allowing us that in depth discovery all from a man made machine.
Microscopes are mostly used in the science field. They are instruments that give us the ability to enlarge small objects so we can have a better look on a larger scale. Microscopes are very accurate and reliable. We are able to look at organisms that would be impossible to look at if we did not have access to these instruments. You can enlarge things to even 100 times its original size which is more than amazing. There are different kinds of microscopes. You have monocular, binocular, and trinocular. Mono being one means that the monocular microscopes only have one eye piece. Binocular is made with the idea of two eyes being able to see. Another word for binocular stereo microscope is stereomicroscopes. When the binocular microscope has a third eye it is known as a trinocular microscope. These types of microscopes are for if there is a second person and there was a recording taking place to capture the image or images that were seen. There is also the monocular compound microscope which should not be confused with a compound lens magnifier. This type of microscope has very different lens that allows for a deeper look at smaller objects. It is fitted with two and sometimes even more convex lens. The monocular compound microscope is greatly used in the science world because it gives access to a more detailed study of microorganisms, tissue and cells.
We open up a whole other world of microorganisms, bacteria, fungi, and viruses where we are able to learn and become knowledgeable in the different types of life living among us. The introduction of the monocular microscopes and the monocular compound microscope has given us the opportunity to open doors that were once closed. We are learning that there are good bacteria and bad bacteria from watching it through these types of lenses. We are saving lives by figuring out the different types of viruses and how to either prevent or cure them. So much has been discovered from these scientific instruments and so much is yet to be discovered.For detailed information abou variety of microscope, click here

See the Invisible With a Fluorescent Microscope

Have you ever wondered how doctors and scientists seem to know exactly how cell divides, what they look like, and what they do? At some point in your life, you may have peeked under a microscope in a biology class. You probably felt the images weren't that interesting or colorful. But if you had done the looking through a  laboratory fluorescence microscope , you would have whistled a a different tune. Why?
Light and Colors
Contrary to the common field microscope that uses reflection and absorption techniques to create magnified images of specimen, the fluorescence microscopes uses light to excite specimens to emit light of longer wavelength. Fluorescence is an intrinsic property of substances where it becomes luminescent when excited by a radiation. Simply put, a fluorescent microscope is a light microscope with extended capabilities and added features. A more intense light is used in microscopy that excites fluorescence in the specimen which then emits a longer light wave length. Scientists use markers to distinguish emitted wavelengths by different colors. This technology shows digitally clear color images of microscopic organisms under probe. This technique of using transmitted light through a specimen is known as Kohler illumination, after the brilliant mind who sought to overcome the limitations of previous technologies, August Kohler.
Fluorescent Microscope in Life Sciences
Unlike metallurgical microscopes used for inspecting ceramics, metals and other inorganic materials, the fluorescence microscope finds its best uses in biology and life sciences. Rapidly expanding observation technique in medicine and biology, a range of more sophisticated techniques has evolved from it. More advanced technologies such as the multiphoton and canfocal microscopies are now combined with chromophore and flourophore advances now make intracellular observations even in unicellular molecules possible. Where the cell was acknowledged to be the smallest biological unit a few decades past, components of the human DNA are no distinguishable observations under these powerful tools.
Some have an inverted frame most suitable for viewing tissue cultures and similar applications. These designs provide illumination using an episcopic optical pathway.
Examples of Fluorescence Microscopes
Olympus BX51 Upright Microscope is a modern design of an epi-fluorescent microscope with a vertical illuminator. The illuminator houses a xenon or mercury arc lamp and a turret of filter cubes. Source light travels through the lamp house through two diaphragms and into the cube holding the excitation and emission filters, as well as a dichroic mirror
Olympus IX70 inverted microscope . This inverted frame uses epi-illumination from an internal lamphouse. Light travels from the lamphouse via a collector lens into a cube holding the filters and a dichroic mirror
Both these examples are professional or research grade equipment. These both show the full range of capabilities a basic illuminating microscope is capable of. There are even more powerful microscopes with far more advanced features using highly advanced techniques. One of the more popular ones, confocal microscopy, now offers point-scanning capabilities with the latest from Olympus, the FluoView Laser Scanning Confocal Microscopy.
Other highly advanced techniques like Multiphoton Excitation Microscopy combine multiple techniques to capture high-definition, three-dimensional, and full color images of specimens. These are the best there is in research equipment, and these will change your life from the very first instant that you use them.

How Modern Microscopes Are Used in the Laboratory

The lab microscope is essential to every scientist, and is used everywhere today from medical labs to schools. Microscopes have been in use since the mid seventeenth century, and were used by Anton Van Leeuwenhoek in his observations of some of the first microorganisms. Those early microscopes had only a single lens and were extremely simple, allowing only the briefest glimpse into the fascinating world of the microcosm.
Today lab microscopes can range from a simple compound microscope with two lenses, to more complex, digital microscopes that come with cameras, motion recorders and laser scanners. Many labs have multiple microscopes, each used for a set purpose, as some work better than others in certain situations.
There are two primary categories of lab microscopes, light microscopes and electron microscopes, though there are many variations in each. A light microscope uses rays of light, magnified and focused through a series of lenses. A common example is the compound light microscope, used to examine thinly sliced sections. With this lab microscope the specimen is lit from beneath, with light passing through clear sections but not the opaque ones. Many times the sample may be dyed to allow certain cellular structures to better absorb light.
One popular light microscope is the biological microscope , used in medical labs as well as clinical laboratories and schools. These are simple microscopes used most often in the studies of viruses, pathogens and other changes in cell tissues as well as bacteria. However, for more complex observations at a smaller level, a different type of lab microscope can be used.
An electron microscope uses an electronically magnified image which allows for a more detailed image of the specimen. By using a particle beam the electron microscope illuminates the object for easier viewing. Many of these microscopes have superior magnification due to the simple fact that electrons have shorter wave lengths than light, allowing for a magnification of almost 1,000,000x rather than the 1000x magnification of light.
Electron microscopes come in several varieties, such as the transmission electron microscope, which, with a high voltage electron beam emitted by an electron gun, can get a magnification of over 50 million times. It is primarily is used in nano-technologies. However, electron microscopes are expensive to operate, requiring high voltages and a water supply for cooling the lenses and pumps. Since vibrations and magnetic fields can interfere with their readings, these microscopes must be carefully housed in stable buildings or underground.
Lab microscopes can even be hooked up to computers which can be useful in enhancing an image. Some come with cameras, 3D functions and LCD monitors to allow you to see your specimen with greater ease. With integrated software you can do more than simply make observations, you can track data, measure the dimensions and shapes of your specimen, and even print favorite images.
Lab microscopes have come a long way since then, growing in complexity as our understanding of the world increases. We are now able to study not just cells, but proteins, electrons, particles and viruses. We are even able to, with the atomic force microscope, now see microorganisms with true, three dimensional surface profiles without having to treat the specimen with either metal or carbon coatings that would damage or change the sample and its readings.

How to Maximize Learning Biology With Your Own Biological Microscopes

So you are a sophomore or a junior in high school or probably you are a Biology major in the university? And you have a few or more biology subjects requiring the use of biological microscopes. Imagine all of the self-study and experiments you can finish faster if you just had one at your disposal.
Microscope and the Layman
What are digital biological microscope ? A microscope is a scientific instrument used to see objects too minute for the naked eye to see without any help. It comes from the Greek word "mikros" meaning small and "skopein" meaning to look or see. The study of investigating small objects or life forms using such an instrument is called microscopy.
Biological microscopes are microscopes specifically dedicated for the study of tiny "microscopic" organisms and or parts of plants or animals like tissue samples or blood samples. These microscopes are not only used for biology classes and studies but also the science in general.
Maximizing the Benefits of Your Own Biological Microscopes
Why spend long and tiring hours doing your experiments and making your science homeworks using your school microscope ? Well not anymore. Biological microscopes come in many shapes, sizes, forms and models. The most important things to remember when you wish to purchase such an item are two things: how much do they cost and how often will you be using it for your school work? If you have this tool readily available you can do your homework or experiments anytime, anywhere you want. However, remember these devices are not really cheap so when you do succumb to the idea of buying one, you really really must need it or you could split the costs with your classmates.
To maximize the benefits for your biological microscopes, you should make sure that your school's courseworks, whether it be homeworks or science experiments, are plentiful and that in most of them, that you can work on. If it is not enough, you can just probably resort to renting it. But if you do have that much science school work to do, it would be prudent to have such instrument lying just around to use at your own time and volition.
These microscopes are not only used for testing or examining animal or plant tissue samples. It is also basically useful for other science experiments and tests such as examining grains of sand or rocks or soil. It can also be used to examine different kinds of seeds and cross-sections of plant leaves or stems.
All in all, there are different applications of the uses of microscopes in your courseworks at school. The whole idea behind buying or renting one is to rid the dependency to go to back to your schools or universities science labs just to use their equipment. There isn't also enough of them to go around for all the students. So make your choice. Dependence on what the school has? Or independence and finish all your school work way before the deadline arrives?
