Calculate the Zernike standard coefficients at the retina surface.

Parameters

backendtype[OptilandBackend]

Reference to the Optiland backend.

field_coordinatetuple[float, float] | None, optional

The field coordinate for the Zernike calculation. When None, the first field in OpticStudio is used. Defaults to None.

wavelengthfloat | None, optional

The wavelength for the Zernike calculation. When None, the first wavelength in OpticStudio is used. Defaults to None.

field_typeLiteral[“angle”, “object_height”], optional

The type of field to be used when setting the field coordinate. This parameter is only used when field_coordinate is specified. Defaults to “angle”.

samplingSampleSize | str | int, optional

The sampling for the Zernike calculation. Defaults to 512.

maximum_termint, optional

The maximum term for the Zernike calculation. Defaults to 45.

Returns
