Understanding how is aperture measured can be confusing at first. This is because aperture is measured in what is known as f-numbers or f-stops, which is the ratio of the lens’ focal length divided by the effective aperture diameter. In other words, if you take a 200mm lens and divide it by a 50mm aperture diameter … See more The simplest explanation for understanding the basics of aperture is this: aperture refers to the opening inside the lens in which light can shine through. Moreover, … See more You may have noticed that lenses are typically labeled with an f-stop number. This is what is known as the lens speed or the maximum aperture available for that lens. See more So what is the point of all these f-stops in regards to answering the question of how is aperture measured? One of the reasons that you want adjustable … See more WebImage Brightness (Fluorescence) λ NA 4 /M 2. Note that in fluorescence microscopy, brightness is also inversely proportional to the objective magnification squared.
