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. WebMar 14, 2024 · The Ray Fan plot is like this. Defocus term is the slope of this line and equals 0.05. Considering the defocus formula DF = focus shift x marginal ray height (10 mm) / focal length (50 mm) gives a 0.5 mm focus shift instead of 5 mm. I am not sure if I have problem with the definition of defocus term or with interpreting the Zemax data. WebThe marginal ray does not change, but the chief ray changes with object height.
