Usb Microscope: Factors when Purchasing a Microscope Biological Microscopes Services A microscope is an instrument used to view objects which are too small to be seen through the naked eye. This is very common in biology since living organisms have microscopic biological structures and it is impossible for one to study these structures without relying on microscopes. History The first ever microscope was introduced in the 1500s. In this era, inventors used glasses from telescopes 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 help popularized the instrument. Because of their scientific study using the microscope, the instrument became a popular tool in scientific research in their time. After that, there were many scientists who followed their path and this helped modernized the instrument further more when manufacturers began modernizing the microscope. Right now, there are many types of microscopes to choose from and each carry specific purpose. What to Consider When Buying a Microscope When planning to buy a microscope, it is very crucial to treat the instrument as a big deal because these things do not come cheap. When buying, consider your needs first. This will help you avoid purchasing the wrong apparatus. 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 more advanced research, high end microscopes which are capable of high levels of magnification is the right instrument for this particular need. Moreover it is also important to consider microscope features. Features which you think will be useful in your endeavor should be your priority. For instance, there are instruments which can be attached to computers using a 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. Finally, ensure that the instrument is durable Since this is considered an investment, it is important that the microscope can last a lifetime. 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. 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. Only when the person understands the concept and components of microscope will he be able to purchase the right instrument. Recommended Site
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. They are used to study blood samples, bacteria, and other small specimens because these require high powers of magnification. A compound microscope can have 3 to 5 lenses. These lenses can magnify objects up to 100x. On the other hand, stereo microscopes are used only to view small objects like leaves, rocks, gems, and insects. In other words, a stereo microscope is a basic instrument capable of magnifying objects up to 40x; the lowest can be 6.5x. Quality Quality of the instrument is very important to consider when purchasing so as to avoid spending top dollars on mediocre apparatus. 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 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 construction, you should also consider other featuresâ€™ qualities. For instance, consider the optical quality of the instrument. This can be determined by assessing the quality of the objective lenses and the quality of the eye pieces. An achromatic lens for example is quite good. These lenses are capable of correcting colors and producing enhanced images. On the other hand there is a sophisticated lens called plan objectives. These lenses are capable of producing high quality and flatter images thus they are used in advanced applications. After sales Service It is also important to take into account the warranty and other after sales service from the maker or the distributor of the product.
