The third common eyepiece is the photocell model. The next common eyepiece is the gas-corrected model. The most common eyepieces are those which use gas-displacement technology to supply light. There are many types of eyepieces, each capable of different tasks. These objective lenses have varying strengths which can be used one at a time by adjusting the revolving nosepiece.Īn instrument called an eyepiece magnifies the object by changing the wavelength of light that is used in the instrument to make it function. On another end of the microscope are objective lenses which are responsible for collecting and concentrating light into the specimen. Also, most microscopes have binocular lenses consisting of two lenses and a prism to split the image on both oculars where you’ll peek through. Aside from the lens magnification, it’s also important to identify the microscope field of view to accurately measure the size of your specimen. The use of different microscope lenses promotes magnification without altering the quality of the image produced. This kind of microscope is typically used in research centers, schools, and hospitals. Without the presence of light, microscopes won’t work. The most basic microscopes used in various institutions today make use of a series of lenses that collect, reflect, and focus light into the specimen, which is the object under inspection. Thanks to this discovery, more breakthroughs and innovations were developed that lead to the microscopes we are using today. Through placing an object at the end of a tube, and placing two lenses on top and bottom of the tube, Zacharias and his father Hans, realized that the object became magnified. It was in the 16th century when the first compound microscope was discovered by and credited to Zacharias Janssen. Microscopy is the scientific field of study which is used to study minute structures and objects by a microscope. What Is A Microscope?Ī microscope, from the Ancient Greek words mikrós or “small” and skopeîn or “to look or see,” is a tool that is used to view smaller objects that the human eye can see. If these items are already difficult to inspect, what more of the smaller parts of an organism and other things that seem almost invisible? This is what microscopes are for. Have you ever wondered how the smallest things look like up close? From one grain of sugar in your coffee, a strand of hair, or your cheek cells, you can’t see these things and examine them closely with just your naked eye.
