optimization.variable.norm_radius

This module provides variable handling for normalization radius parameters.

The normalization radius is used in certain optical surface representations (like Forbes polynomials) to control the scaling of the surface coordinates. It contains the NormalizationRadiusVariable class for use in optimization problems.

Classes

NormalizationRadiusVariable(optic, ...[, scaler])

Represents a variable for the normalization radius of a surface.

class NormalizationRadiusVariable(optic, surface_number, scaler=None, **kwargs)[source]

Represents a variable for the normalization radius of a surface.

get_value()[source]: Returns the current value of the normalization radius.

inverse_scale(scaled_value)

Inverse scale the value of the variable.

Parameters:: scaled_value – The scaled value to inverse scale

scale(value)

Scale the value of the variable for improved optimization performance.

Parameters:: value – The value to scale

update_value(new_value)[source]: Updates the value of the normalization radius.
