WebDec 17, 2024 · As light passes through the surrounding medium in a light microscope, a single point of light (called a fluorophore) will appear blurry. The size of the blur is known as the point-spread function. When two structures are closer than the diffraction limit, they will appear as a single blur rather than two separate structures. WebThe microscope we most often see is called a light microscope. It uses a light to help us look at the tiny details of the thing we are investigating (our sample). We can use a light microscope to study cells, parasites and some bacteria. Look at the image of a microscope, and click on each part to find out how it helps us to investigate our sample. WebA microscope uses light in two ways: 1. To illuminate the specimen under observation and allow it to be seen. 2. To collect images of the specimen and provide a digital record of its structure.
