There are different types of microscope you need to know before you purchase a new one. There are types specifically made for biological purposes while there are ones made for teaching students. These microscopes come in different features as each is made according to purpose. So, whether you plan to buy new or used laboratory microscopes, the first thing you want to do is find out what you really need.
Compound Microscope
Compound microscope, as what the term conveys, has two eyepieces. This is the perfect type that can be used by biologists and botanists as they study the minute cells of every living thing. These include the microorganisms found in plants and animals. Compound microscopes allow magnification for up to 15 times. It is usually combined with three lenses, but there are recent models that have four objective lenses. This type of microscope is also used by students as it is affordable and easy to use.
Stereo Microscope
Unlike the compound type, stereo microscope allows higher magnification for up to 100 times. This microscope has two optical paths with different angles so a specimen can be viewed at a 3-dimensional effect. The good thing about stereo microscope is that it can be used with fixed zoom or with adjustable zooms. It also allows better view of the photosynthesis.
Digital Microscope
Since it is made digital, no eyepiece is required for this type. This is one of the highest technological advances the world has today. Digital microscope was invented in 1986 in Japan. It is electronically powered with a computer to view microorganisms. It works by connecting a USB cable to a computer, in which software is used to magnify the specimen. The advantage of this type is that the viewed specimen can be captured and easily shared via the internet or other means.
USB Computer Microscope
For hobbyist, children, and professionals-on-the-go, the USB computer microscope may be the most convenient type to use. However, it does not promise an accurate feature unlike the other types. The USB Computer Microscope can be used in any specimen but the magnification only is as good as a standard microscope. This is used by connecting the USB port into the computer screen. The images can be captured, magnified or edited via software.
Electron Microscope
There are two types of electron microscope. These are the transmission electron microscope (TEM) and the scanning electron microscope (SEM). The first type allows producing one nanometer of specimen while the other is 10 times less powerful than TEM. The electron microscope is used in different applications including chemistry, topography, biology, chemistry and others.
Other types of laboratory microscopes are pocket microscopes, scanning probe and acoustic. Each of the type has a specific feature specially made for a purpose. When it comes to choosing your own microscope, it is best to know these types and match it well to how you are going to use it. The Tottleben Scientific can help you decide on the different types you can use. They also have Used Laboratory Microscopes you can purchase.
