Marginal ray height是什么意思
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. WebIf the marginal ray height in a certain aperture is -5 mm and the chief ray height is 10, what is the aperture diameter required to avoid vignetting? Show transcribed image text. Expert Answer.

WebFrom the Solve Type menu, select Marginal Ray Height and hit return. This is a “solve”, i.e. a calculation done by OpticStudio to solve for a property of the lens. In this case, we are setting the thickness from the back surface of the lens (#2) to the image (#3) such that the marginal ray which just hits the outer edge of the stop is ... 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.
