Go to Common Results Node Settings for links to information about these sections: Data, Title, Range, Coloring and Style, and Inherit Style. For Optical Aberration plots, only Intersection Point 3D datasets are allowed as inputs.

The Optical Aberration plot is available with the Ray Optics Module.

Select the Filter by wavelength check box to exclude all rays except those of a specified vacuum wavelength. If this check box is selected, enter a Wavelength (default: 632.8 nm) and a Tolerance (default: 1 nm). If the difference between the specified wavelength and the vacuum wavelength of a ray exceeds this tolerance, then the ray will be ignored.

Select the Filter by release feature index check box to exclude all rays except those released by a specific physics feature. Then enter an integer value for the index; the default is 1. This field is 1-indexed, meaning that 1 corresponds to the first ray release feature, 2 is the second ray release feature, and so on.

Select the Filter by number of reflections check box to include rays only if they have reflected a specified number of times. Then enter an integer for the number of reflections; the default is 0. For this option to work correctly, it is necessary to select the Count reflections check box in the settings for the Geometrical Optics interface, before running the study.

|
Select the Filter by additional logical expression check box to include rays if they satisfy another user-defined expression. The expression is considered to be true if it returns a nonzero value. The default expression is 1, which would cause all rays to be included.

For Direction based, the normal to the focal plane is the average ray direction. This average is taken over all rays that satisfy the filter criteria given by the Filters section above.
|
•
|
For Position based, the normal to the focal plane is determined such that the ray positions are as close to the plane as possible. If the rays are stopped at a curved surface, the normal computed in this way may differ significantly from the surface normal.

|
For User defined, enter values or expressions for the normal vector components directly. By default, the z-axis is used.

If All is selected, all Zernike polynomials up to the specified Maximum polynomial order are included in the plot.
|
•
|
If All higher-order terms is selected, all Zernike polynomials up to the specified Maximum polynomial order are included in the plot, except for the terms of order 0 and 1. These terms indicate misalignment or misplacement of lenses within an optical system and are less useful for measuring lens quality.
|
•
|
If Select individual terms is selected, check boxes appear for all Zernike polynomials. The common names of the polynomials are included where applicable. Select or clear the check boxes to determine which terms should be included in the plot. You can also use the Select All and Clear All buttons to quickly select or clear all of these check boxes at the same time.

A list of Zernike polynomials and their derivation, properties, and references are included in the Ray Optics Modeling chapter of the Ray Optics Module User’s Guide.
