It is a function that calculates the sharpness or fuzziness of an image. It is important to understand several terms before we can fully describe MTF. Spatial Frequency is defined as one divided by the period of a repeated structure. A picture would probably be helpful here.

How much light can my spectrometer capture? - Ibsen …
The f-number accurately describes the light-gathering ability of a lens only for objects an infinite distance away. This limitation is typically ignored in photography, where f-number is often used regardless of the distance to the object. In optical design, an alternative is often needed for systems where the … See more In optics, the f-number of an optical system such as a camera lens is the ratio of the system's focal length to the diameter of the entrance pupil ("clear aperture"). It is also known as the focal ratio, f-ratio, or f-stop, and is very … See more The f-number N is given by: where $${\displaystyle f}$$ is the focal length, and $${\displaystyle D}$$ is the diameter of the … See more Depth of field increases with f-number, as illustrated in the image here. This means that photographs taken with a low f-number (large … See more The camera equation, or G#, is the ratio of the radiance reaching the camera sensor to the irradiance on the focal plane of the camera lens: where τ is the … See more The word stop is sometimes confusing due to its multiple meanings. A stop can be a physical object: an opaque part of an optical system that blocks certain rays. The See more Computing the f-number of the human eye involves computing the physical aperture and focal length of the eye. The pupil can be as large as 6–7 … See more The system of f-numbers for specifying relative apertures evolved in the late nineteenth century, in competition with several other systems of aperture notation. Origins of relative aperture In 1867, Sutton and Dawson defined "apertal ratio" as … See more WebThe spectrometer has an f number of 3.5 which means that the ratio of the distance from the final lens to the slit to the diameter of the lens must be less than or equal to 3.5 to make sure that the grating is filled. Basically, this means that your lens should be 15 cm or less from the spectrometer. We get around this in the absorption section ... how to say gwion
