Best Microscope for Research

A microscope for research can be an expensive gadget to have in your lab, yet this piece of equipment is essential if you are going to carry out your work properly.

Many different types are on the market today from which to choose. For example, there is the confocal microscope, which uses lasers, and there is the transmission electron microscope, which uses the excitability of electrons to see the images.

No matter what type of microscope you use for in your laboratory, research has certainly come a long way since 1674.

Biologists who are studying various diseases in the hope of finding a cure make use of four principle types of microscope in the course of their research.

These are the:

• Compound microscope
• Dissection microscope
• Scanning electron microscope
• Transmission electron microscope

Both the scanning electron and transmission electron microscopes utilize electrons and their excitability in order to view objects. The scanning microscope sees images in three dimensions while the transmission microscope sees them in two dimensions. As its name suggests, a dissection microscope is used for close up work and magnifies smaller specimens so that they can be dissected. Compound microscopes are the most popular and allow you to view the image at the cellular level, unlike the dissection scope.

Other types of microscope for research are the confocal microscope and the atomic force microscope. The confocal uses lasers in order to view images that are then viewed on a computer monitor. The atomic force scope is similar to the SEM, but while the items in the scanning scope use a vacuum, an atomic scope does not. These are both very high tech scopes that can make research very interesting with the images that can be viewed.

Using a microscope for research has proven to be an invaluable tool for many researchers. Since the beginnings of microscopy and its discoveries, the world of microscopes has advanced beyond what the founders first imagined. Understanding these magnifying instruments can prove to be hard for the average person because of their highly specialized and intricate parts. However, the work that is produced can save a person's life or that of a loved one. Microscopes are a needed necessity in today's world, and the more high tech they can become, in order to help us humans, the better.

Advantages of a Scanning Electron Microscope

A scanning electron microscope or SEM can prove to be an invaluable asset in the high tech world of research. No longer is a scientist limited to just using light microscopes in order to view their specimens.

The SEM's of today offer many advantages over their counterparts. However, they also come with a hefty price tag, but their quality of viewing is the best. By understanding the advantages, you can better determine if this type of microscope will be worth the investment.

One of the main advantages of owning a scanning electron microscope is the depth of field that it offers the researcher. For those who do not understand what depth of field is, let us explain. Depth of field is how one sees a specimen. The SEM offers the observer the chance to see a larger part of the object being studied than any other microscope. The scanning microscope is invaluable when it comes to the amount of an object that can be viewed on microscope slides. One can see an entire specimen instead of just a small part, which is what a light microscope offers.

Numerous additional advantages exist that would make choosing a scanning microscope for the laboratory a sound investment. The microscope offers exceptionally high resolution of images and this is vital in today's world of research. The microscope also offers a superior level of magnification than the majority of other microscopes. This in turn helps to ensure that the images are viewed in minute detail. This can assist in the study of a variety of viruses as well as parts of an animal or insect. Because the microscope uses electromagnets as an alternative to lenses, the user has the uncanny ability to see items at a much closer range. This can prove invaluable when studying and trying to find cures for diseases.

A scanning electron microscope is crucial to have as a piece of laboratory equipment if people are doing any type of research. The microscopes are great for seeing images "up close" that otherwise would be non-existent for the person viewing. However, they are extremely expensive, and if you are serious about owing and operating a scanning microscope, then you should definitely do your homework and decide if this type is right for your laboratory and the images to be studied.
