They are affordably priced and have low maintenance costs. Light microscopes are simple to use and do not require the use of high voltage power or filaments. Images are viewed directly with the human eye through the eyepiece. There are no special settings required for the room where the microscope is housed. ![]() They present flat images in color, but it is possible to see living processes like cell division and microscopic pond life. ![]() Light microscopes tend to have low resolving power, with a poor surface view. Focusing the image is done by mechanically adjusting the lens position. That may sound impressive, but it’s on the low-end of what microscopes can do. The specimen is then mounted on the glass slide, and can be magnified up to 1,500x. The specimen is stained with colored dyes to make it properly visible. The specimen can be 5 micrometers or thicker, and does not have to be dehydrated before looking at it. Generally, it can be done within a few minutes to a few hours. It doesn’t take a lot of work to prepare specimens for the microscope. You can use a variety of specimen types, including fixed or unfixed, stained or unstained, living or dead. Light microscopes are lightweight and fairly small. The lenses are made of glass, and the image is formed by the absorption of light. It uses light, at approximately the 400 to 700 nm wavelength to illuminate the objects under view. What Is a Light MicroscopeĪ light microscope may also be referred to as an optical microscope. It’s crucial to understand what they are and how they are different, to ensure your lab has the right equipment for your needs. ![]() There are many types of microscopes available on the market today, with two of the most common being light microscopes and electron microscopes. What most people don’t know is that the first compound microscope was created in 1590, by Dutch spectacle makers Hans and Zacharias Janssen. Microscopes are high-tech equipment that enable us to see the world at an entirely different level.
