WebSince the EP is the reference position for the FOV, this defining ray becomes the chief ray of the system. For distant objects, assuming a thin lens in air with the stop at the lens: The system FOV can be determined by the maximum object size, the detector size, or by the field over which the optical system exhibits good performance. WebDec 6, 2024 · There is another case where only the Huygens’s calculation can be used: if Chief Ray cannot be traced through the system, then a Chief Ray-centered reference sphere cannot be created. The reference sphere is essential for many wavefront calculations. In this case, the Huygens PSF and MTF calculations can be used.

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 the prism in figure 1.5 is the tip of a lens shows us how the phenomenon occurs in a lens like one from figure 1.4. WebThe ray through the geometrical center of the lens produces a point in the paraxial focal plane. The top and bottom rays (the meridional rays) from the circles of increasing size produce points which define image planes that are successively closer to the lens; this is a consequence of spherical aberration. can a hot water tank explodeWebJohn Hagopian Engineering.

WebThe central ray of a beam is known as the chief ray. When the chief rays from all of the angles are parallel, we have a condition known as telecentricity; the lens is said to be telecentric. Although telecentricity is not required in a conoscope lens, it is very useful when turning the lens into a scatterometer.
