Video Microscope: Qualities of a Good Microscope Biological Microscopes Information Buying a microscope can be confusing especially to the uninitiated or for first time buyers which is why it is important to read and study the different aspects of the instrument. Today, there are so many types of microscope in the market. By studying the basics of microscope and its function, will be the only time one can purchase the right instrument. Below is an overview of topics which you will encounter when purchasing a microscope. Read and understand them in order to make the right purchase. Compound or Stereo Compound microscopes are capable of high levels of magnification thus they are usually used in viewing smaller specimens. Blood samples, bacteria, and other small object are usually studied under a compound microscope. These specimens require high powered magnification which only a compound microscope can provide. A compound microscope can have 3 to 5 lenses. These lenses can magnify objects up to 100x. Meanwhile, stereo microscopes are used to view small objects. Leaves, rocks, gems, and insects only require basic magnification. In other words, a stereo microscope is a basic instrument capable of magnifying objects up to 40x; the lowest can be 6.5x. Quality It is important to take into account the quality of the instrument. This is to avoid spending huge money on mediocre instruments. Usually, microscopes made in Germany and Japan are the most sought after because their quality is topnotch however, they are expensive to procure too. If your budget is limited, there are budget friendly microscopes with amazing quality too but they may lack features which are basic in high end microscopes. Apart from the overall construction, it is important to consider the optical quality as well. You can determine the optical quality by looking at the objective lenses and the eye pieces of the apparatus. These will help you purchase the right instrument for your needs. An achromatic lens is quite good since it can correct colors as well as produced an enhanced image. For more sophisticated application, there are high end lenses called plan objectives which produce better quality and flatter images. After sales Service To get the best value ask for a warranty. A good instrument must come with a warranty from the manufacturer or distributor. This is helpful if you are to buy online or abroad and require the item to be shipped to your address. This will keep you confident in your purchase knowing that the manufacturer or seller provides warranty and replacement for damaged parts. A microscope is an instrument for viewing. It is mainly used in examining objects which are
too small for the eyes. Microscopes are usually used in the field of science. It is because this subject usually deals with small or microscopic objects. One of the fields which microscopes are used heavily is in biology. In this subject, viewing biological structures would be impossible because most of them are very tiny or microscopic. www.digital-usb-microscopes.com History The first ever microscope was developed in the 1500s when glasses from telescopes were used to view small objects. Galileo also contributed in the development of microscope which was later referred to as the compound microscope. Meanwhile scientists Robert Hook and Antonie Van Leeuwenhoek were the first people to use the instrument in viewing biological objects and this help popularized the instrument further. Due to the significant discoveries through the use of microscope, manufacturers began to modernize the instrument so it could be used extensively in research. Today, there are not just one type of microscope available in the market but there are dozens of these instruments which can be used in different fields other than biology. What to Consider When Buying a Microscope When planning to purchase a microscope, it is important to consider this instrument as an investment, after all these things come with a hefty price. When buying, consider your needs first. This will help you avoid purchasing the wrong apparatus. For example, if you are to examine leaves, bugs, rocks, and gems, this calls for a basic microscope. In this scenario the perfect choice will be a stereo microscope. For more advanced research, high end microscopes which are capable of high levels of magnification is the right instrument for this particular need. In addition, you should also consider features in these instruments which you will find useful in your research. For instance, there are instruments which can be attached to computers using a USB. This is very convenient if you want to review different objects you have examined under the USB microscope because you can take images and store them in your PC.
