WebRelative Illumination (RI) is a way to represent the combined effects of vignetting and roll-off in an imaging lens and is given as a percentage of illumination at any point on the … WebThe height of the chief ray at the image plane defines image size. If lateral color exists in the lens system, this chief ray is dispersed, causing the differing wavelengths to be imaged at different heights on the image plane. The result is a chromatic, radial blur for off-axis image points. In the case of a simple lens with the chief ray ...

Geometrical Optics 101: Paraxial Ray Tracing Calculations
Web5.3 Marginal and Chief Rays: • For an axial object point, the ray that just brushes the edge or rim of the stop (and entrance pupil and exit pupil) is called the marginal ray . • Now consider the off-axis point that defines the maximum field angle. The ray from this point that passes through the center of the stop is called the chief ray. WebThe heights of the marginal ray and the chief ray can be evaluated at any z in any optical space. When the marginal ray crosses the axis, an image is located, and the size of the image is given by the chief ray height in that plane. Whenever the chief ray crosses the axis, a pupil or the stop is located, and the pupil WebApr 13, 2024 · 4 Year Degree. Internal Number: S01140.
