WebAs with other aberrations, a lens with a larger field of view will generally exhibit a larger amount of distortion. A fisheye lens or ultra wide-angle lens produces strong visual distortion. Figure 3 shows the distortion in a fisheye lens with effective focal length of 3.0mm. Figure 4 shows a simulated image of a wide angle lens with -50% ...

WebAperture and Field Stops Stops determine the light-collecting area and field of view of an optical system. We can find the stops by tracing two rays called the marginal (or axial) …
WebIn optics, the numerical aperture ( NA) of an optical system is a dimensionless number that characterizes the range of angles over which the system can accept or emit light. WebThe field of view of an optical imaging instrument is often limited by an intentionally created field stop. This is an optical aperture, e.g. in the form of a diaphragm, which is placed in an image plane or close to such a …
