1D Penumbra Infl RightΒΆ
The tradional parameters for defining the penumbra do not work for FFF beams. The similar 80%-20% penumbra based on the inflection point is calculated as the distance between 1.6 times the inflection point value to 0.4 times the inflection point value for the right penumbra.
\[PenWidthINFL = |d(P_{0.4}) - d(P_{1.6})|\]
\[P_{0.4} = Y_{infl} \cdot 0.4\]
\[P_{1.6} = Y_{infl} \cdot 1.6\]
Where d(P 0.4) and d(P 1.6)) are the linear distances to 0.4 and 1.6 times the inflection point value respectively as defined above.
