Traditional microscopes There are two kinds of traditional microscopes: stereo, or compound biological microscopes and each is used for a different purpose. Compound microscopes include Binocular and Monocular. They have high magnification up to X sometimes as high as X and are used to examine microscope slides, which have a very thin specimen on them.
Light passes through the specimen and is viewed in the eyepiece of the microscope. You can buy specially prepared slides, or prepare them yourself. One of the most common slide preparations is onion scrapings, which are placed on the slide and the onion cells can be clearly viewed. Monocular microscopes are easier to use but binocular microscopes are better if you are spending a long time looking into the eye piece.
Stereo microscopes are low magnification normally 20X and 40X. And since it functions as an endoscope, you can also use this microscope to dark areas and objects that you otherwise will have a hard time observing without the use of a more advanced microscope that costs thousands of dollars. And, it has a decent frame speed and focus range, as well as a somewhat refined focusing ability to get you the clearest images.
In fifth place is the Plugable USB digital microscope that features a flexible gooseneck arm for maximum mobility and specimen viewing range. As the brand name tells you, this is a plug and play microscope that you connect to your computer via a USB 2. This is a microscope that is great for classroom and field applications. If you are looking for a high definition yet cost effective digital microscope that you can use for a variety of purposes, the Opti-Tekscope advanced CMOS sensor digital microscope is an excellent option, especially since you can also use it as an endoscope.
It features a fully customizable brightness control, as well as macro and fine focusing capabilities. With this digital microscope, you can study lots of specimens such as rocks, plants, insects, precious stones, and coins, or do basic electronic work like repairing or making circuit boards. This is a microscope that you can bring around anywhere, anytime.
An affordable yet worthy alternative to expensive digital microscopes is the Opti-Tekscope true HD digital microscope, which comes up at less than a hundred dollars. So, if you are a scientist and collector at heart, this is a great choice for you. You can even use this microscope for basic engineering works like making circuit boards. It has a sturdy aluminum frame that is durable and lightweight, a wide specimen stage plate that lets you work with large objects, and various other great features.
Last but not the least, if you are in the market for a small and handheld pocket microscope, you might also want to consider the Firefly handheld polarizing digital microscope, which has a decent magnification of up to x for digital, and 50x for native. This digital microscope acts as a simple light microscope, a dermascope , and an endoscope all in one tiny package that fits on the palm of your hand.
Plus, it features twelve different polarizing settings in varying distinct levels of polarization, making it excellent for certain microscopy techniques such as digital epiluminescence microscopy. There are many different types of digital microscopes, all with different specs and features, and as such, it can be quite daunting to choose the right one that will give you the performance that you need.
So, in order to help you make the right decision on buying the best digital microscope for you, here are the most important factors that you need to consider before buying:. First things first, you need to ask yourself whether you even need a digital microscope in the first place, and how you will benefit from owning one. This means clearly knowing what a digital microscope is, and how it functions. To put it simply, a digital microscope is just about any type of microscope that has a digital component in the form of a camera and a computer software.
This allows you to conveniently and comfortably study various specimens, especially those that require long term observation. This technology lets you capture and immortalize the fine details of the specimen under study, and more importantly, record the progress, life, and interactions of that specimen over a certain period of time. As with any type of microscope, digital microscopes can either be entry level, mid range, or high end. The microscope software will make the optimization process as simple as possible and ensure the varying factors, like magnification, illumination, and exposure, all work together as they should in order to produce the best images possible.
Lighting options: Lighting is one of the most important components of a good microscope. The secondary source is via the eyepiece lens. Total magnification is achieved by multiplying the magnification power of the objective lens by that of the eyepiece lens. For example: Standard eyepieces have a power of 10x.
When using a x objective lens, the total magnification would be 1,x. Second, and perhaps most important of all, do not fall into the trap of being attracted by high levels of magnification. Microscopes fall into two basic categories: Compound or Stereo, often referred to as high power or low power, respectively. You will need a compound microscope if you are viewing "smaller" specimens such as blood samples, bacteria, pond scum, water organisms, etc. The reason is that such specimens require higher powers of magnification in order to see the detail.
For this reason, a compound microscope is also known as a high power microscope. Typically, a compound microscope has objective lenses that range from 4xx. Assuming 10x eyepieces and x objective, the total magnification would be 1, times. Compound microscopes are also integrated systems in the sense that the microscope body and base form an integrated unit.
When considering a compound microscope, you will also need to decide on whether you want a monocular, binocular or trinocular microscope.
That is to say, a microscope with one, two eyepieces or one with two eyepieces and a third, trinocular port. Magnification : Monocular microscopes work efficiently for up to X total magnification.
For higher magnification levels, a binocular microscope is required. Comfort : Most people find binocular microscopes more ergonomic and easier to use than monocular. Young children, on the other hand, find monocular easier to use. Price : While the price ranges overlap, typically a monocular microscope is the least expensive type of microscope with trinocular being the most expensive.
Application : Most monocular microscopes do not include a mechanical stage, which is useful for more sophisticated applications. Most binocular microscopes do include a mechanical stage. A trinocular microscope is typically used when a third trinocular port is required for microphotography.
You will need a stereo microscope to view more substantial specimens such as insects, bugs, leaves, rocks, gems, etc. Typically, such specimens require lower power, magnification ranges from 6. Hence they are also known as low power microscopes.
By definition, a stereo microscope has at least two eyepieces binocular , and provides a three-dimensional image of the specimen. They are available in one of two configurations: dual power or zoom. In the first instance, the microscope has two magnification options, for example 20xx. In a zoom microscope, there is a continuous zoom range from the lowest power to the highest power.
For example, from 6.
