How Do You Identify Parts On A Microscope?
The compound light microscope is the microscope most frequently employed in studying microbes. Compound light microscopes use multiple lenses to magnify samples anywhere from 40 times, with the weakest objective lens, to 1,000 times, using the oil emersion lens. Using a compound light microscope, objects as low as 0.2 micrometers apart can be distinguished. In order to properly utilize a microscope you must first know the parts of the microscope and what they do. Notice the lens on the top of the microscope. This is known as the ocular lens and it is set in the eyepiece. The eyepiece is what you look through to see the slides under the microscope. Notice the three to four lenses located on the rotating nose piece. These are called objective lenses and they are used to change the magnification of the microscope. Compound light microscopes commonly have a scanning lens which magnifies four times, a low power lens which magnifies 10 times, a high dry lens which magnifies 40 times, and an
