How Do You Identify Parts Of A Compound Microscope?
The compound microscope is one of the most well-known and often-used research tools in biology. Bacteria, the smallest organisms considered to be alive, can be observed under a measly 100-times magnification; whereas the typical compound microscope ranges from 40-times to 1000-times magnification with a resolution of 100 nanometers; that is to say they can distinguish between objects 0.1 micrometers apart. Turn the rotating nose piece which has multiple lenses mounted on it. These objective lenses are used to change the magnification of the microscope. The scanning lens magnifies 4 times, the low power lens magnifies 10 times, the high power lens magnifies 40 times, and the oil immersion magnifies 100 times. The oil immersion lens can only be used with immersion oil, which allows for better resolution. Look through the lens set in the eyepiece on the top of the microscope. This is the ocular lens and it magnifies objects to 10 times their normal size. In combination with the low power
