Microscope Digital: What to Consider When Purchasing a Microscope Usb Microscope 101 A microscope is an instrument used to view objects which are too small to be seen through the naked eye. This instrument is usually used in scientific research and in other fields which deals with viewing and examining microscopic objects. For instance, the equipment is very common in studying living organisms because these organisms have biological makeup which are impossible to view without using an advanced viewing apparatus like a microscope. History The first microscope was introduced in the 1500s when inventors used glasses from the telescopes and converted it into an instrument to view small objects. Galileo also helped modernized the early microscope. He used convex lens and concave lens to give the instrument more power in viewing small objects. Meanwhile, Robert Hook and Antonie Van Leeuwenhoek popularized the invention when they used the instrument in studying biological structures. 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, make sure that you have taken into account your need so as to avoid purchasing the wrong instrument. 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 examining smaller objects like blood, bacteria, and more, you need a microscope that can magnify these things a hundred times. In this scenario, the compound microscope is the right instrument to purchase. In addition to your need, features or components of the instrument is also important to consider especially if you have a particular feature in mind. For example, There are microscopes which can be connected to personal computers today. Via USB you can now attach your microscope to a PC, laptop, or tablet. This type of apparatus is helpful especially if you are viewing hundreds of specimens because you can now store images of your research directly in your PC. Lastly, make sure that the construction is strong. Although fragile, it must possess certain degree of durability. Since this is considered an investment, it is important that the microscope can last a lifetime. However, since wear and tear is usually expected in most things, it will be nice if the instrument comes with a warranty from the manufacturer Purchasing a microscope can be a confusing task especially to a person who does not know the instrument very well. This is the reason why it is important to study the concept and understand the different parts 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 are important categories which you need to consider very well if you want to make the right choice. Compound or Stereo Compound microscopes are usually employed in advanced applications. It is because these instruments are capable of providing high levels of magnification to view 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. Usually, a compound microscope has 3 to 5 lenses with range 4x to 100x. Stereo microscopes are used in viewing leaves, rocks, gems, and insects since these objects are not really small compared to specimens viewed in compound microscopes. Stereo microscopes when compared to compound microscopes is just average. Their lenses have range from 6.5x to 40x. Quality It is important that you purchase a brand that is of quality to avoid spending money on a mediocre instrument. 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. This can be determined by assessing the quality of the objective lenses and the quality of the eye pieces.
