WebNov 21, 2013 · A chief ray is the ray from an off-axis object point which passes through the center of the aperture stop of an optical system. The chief ray enters the optical system along a line directed towards the midpoint of the entrance pupil, and leaves the system along a line passing through the center of the exit pupil. WebLCA is the result of dispersion of the chief ray. Thus, when a lens exhibits LCA, light is affected very similarly to light traveling through a dispersive prism (figure 1.5). Imagining …
WebMaximum chief ray angle upon image plane CRA < 30 ° The system is downscaled by a factor of F= 0.161. Thus, all geometrical values such as radii, thicknesses and semi-diameters are multiplied by this factor F. This results in a system having a focal length of f′ = 28 mm ×0.161 = 4.52 mm. WebMar 31, 2024 · The sagittal plane is the plane that is orthogonal to the tangential plane with which it intersects along the chief ray. For a rotationally symmetric system, field points along the y axis alone define the system’s imaging properties, and these points should be used. In this case, the tangential plane is the YZ plane, and sagittal plane is the ...

When the chief ray has a zero slope (parallel to optical axis) the system is telecentric which is not at all the same thing as collimated. 3. hildesheim parkinsonWebSince the chief rays are all parallel, the front optics must be at least as large as the field of view because the chief rays do not change height after leaving the lens.
