colour.plotting.plot_multi_layer_thin_film(n: ArrayLike, t: ArrayLike, theta: ArrayLike = 0, shape: SpectralShape = SPECTRAL_SHAPE_DEFAULT, polarisation: Literal['S', 'P', 'Both'] | str = 'Both', method: Literal['Reflectance', 'Transmittance', 'Both'] | str = 'Reflectance', **kwargs: Any) → Tuple[Figure, Axes]

Plot reflectance and/or transmittance of a multi-layer thin film stack.

Parameters:

• n (ArrayLike) – Complete refractive index stack \(n_j\) including incident medium, layers, and substrate. Shape: (media_count,) or (media_count, wavelengths_count). The array should contain [n_incident, n_layer_1, …, n_layer_n, n_substrate].

• t (ArrayLike) – Thicknesses \(t_j\) of the layers in nanometers (excluding incident and substrate). Shape: (layers_count,).

• theta (ArrayLike) – Incident angle \(\theta\) in degrees. Default is 0 (normal incidence).

• shape (SpectralShape) – Spectral shape for wavelength sampling.

• polarisation (Literal['S', 'P', 'Both'] | str) – Polarisation to plot: ‘S’, ‘P’, or ‘Both’ (case-insensitive).

• method (Literal['Reflectance', 'Transmittance', 'Both'] | str) – Optical property to plot: ‘Reflectance’, ‘Transmittance’, or ‘Both’ (case-insensitive). Default is ‘Reflectance’.

• kwargs (Any) – {colour.plotting.artist(), colour.plotting.render()}, See the documentation of the previously listed definitions.

Returns:

Current figure and axes.

Return type:

tuple
