Zernike Coefficients Variable Module

This module contains the class for a Zernike coefficient variable in an optic system. The ZernikeCoeffVariable class is a subclass of the PolynomialCoeffVariable class that represents a variable for a Zernike coefficient of a ZernikeGeometry. It is used in the optimization process for Zernike geometries.

Classes

ZernikeCoeffVariable(optic, surface_number, ...)

Represents a variable for a Zernike coefficient of a ZernikeGeometry.
class ZernikeCoeffVariable(optic, surface_number, coeff_index, scaler=None, **kwargs)[source]

Represents a variable for a Zernike coefficient of a ZernikeGeometry.

Parameters:

  • optic (Optic) – The optic object associated with the variable.

  • surface_number (int) – The index of the surface in the optical system.

  • coeff_index (int) – The i index of the Zernike coefficient.

  • scaler (Scaler) – The scaler to use for the variable. Defaults to IdentityScaler().

  • **kwargs – Additional keyword arguments.

coeff_number

The index of the Zernike coefficient.

Type:

int
