Stereo Microscope: How to Buy a Microscope Stereo Microscope Services A microscope is an instrument for viewing. 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. 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 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. After that, there were many scientists who followed their path and this helped modernized the instrument further more when manufacturers began modernizing the microscope. 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 purchasing a microscope, it is important to approach it with caution. After all, these instruments are quite expensive to procure and maintain. When purchasing, make sure that you consider your need so as not to overestimate or underestimate your purchase. For instance, if you are going to use it at home for school purposes, you can purchase a basic type since this will be enough to provide for your needs. 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, you should also consider features in these instruments which you will find useful in your research. For instance, there are microscopes which can be connected to personal computers via USB. This is very effective when you are viewing several specimens in a day. With the help of a USB connector, you can now store images of your research in your PC. Lastly, make sure that the construction is strong. Although fragile, it must possess certain degree of durability. Since it is an investment, it is only normal to seek an instrument which could last long. In addition, it is very expensive to purchase too. However, since wear and tear is impossible to avoid it will be wise to seek a warranty. This is so you will not be spending premium if parts will break or sustain damage. 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. When a person is able to understand the whole equipment and how it functions, that is the time he will be able to purchase the correct microscope. Below are topics that discuss different aspects and components of the microscope so you will understand and hopefully make the right choice. Compound or Stereo Compound microscopes are used in advanced applications due to the high levels of magnification it provides. 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. Meanwhile, stereo microscopes are used to view small objects. Leaves, rocks, gems, and insects only require basic magnification. Stereo microscopes when compared to compound microscopes is just average. Their lenses have range from 6.5x to 40x. Quality It is important to take into account the quality of the instrument. This is to avoid spending huge money on mediocre instruments. Usually German and Japanese brands are the most sought after because the construction is really excellent but the downside is they are quite expensive to own. If you have a limited budget, there are quality microscopes in this range too however, you cannot expect these to have the same features of the high end ones. Apart from the quality of the body, it is also important to consider the optical quality. This can be determined by assessing the quality of the objective lenses and the quality of the eye pieces. For example, an achromatic lens is already enough because it can correct colors and enhance images of the specimens. However, there is a much higher lens than the achromatic called plan objectives and this is used in advanced applications because they produce quality and flatter images.
