- class LayerThicknessVariable(stack: ThinFilmStack, layer_index: int, apply_scaling=True, **kwargs)[source]
Represents a variable for a thin film layer thickness.
This class inherits from VariableBehavior and provides specific functionality for optimizing the thickness of individual layers in a ThinFilmStack.
- Parameters:
stack (ThinFilmStack) – The thin film stack containing the layer.
layer_index (int) – The index of the layer in the stack (0-based).
apply_scaling (bool) – Whether to apply scaling for optimization. Defaults to True.
**kwargs – Additional keyword arguments passed to parent class.
- stack
The thin film stack.
- Type:
- layer_index
The index of the target layer.
- Type:
int
- get_value() float[source]
Returns the current thickness value of the layer in micrometers.
- Returns:
The current thickness value in μm.
- Return type:
float
- inverse_scale(scaled_value: float) float[source]
Inverse scale the thickness value.
Converts from scaled representation back to micrometers.
- Parameters:
scaled_value (float) – The scaled value to inverse scale.
- Returns:
The thickness value in μm.
- Return type:
float
- scale(value: float) float[source]
Scale the thickness value for improved optimization performance.
Converts from micrometers to a scaled representation that’s better conditioned for numerical optimization.
- Parameters:
value (float) – The thickness value in μm to scale.
- Returns:
The scaled value.
- Return type:
float
- property thickness_nm: float
Get the current thickness in nanometers.
- Returns:
The current thickness in nm.
- Return type:
float
