Number of conducting sheets in the stack. Higher counts deepen the interference pattern.
8
Light rays entering simultaneously. Must be ≥ layers.
0.20
Reflected power of a single ray/layer at normal incidence. 0 = clear, 1 = perfect mirror.
0.95
Fraction of maximum absorption at the given reflectance. Higher darkens transmission.
1.00
Strength of nonlinear quantum interaction terms. Sign changes the colour pattern.
Reflection and transmission peak at the same angle for large layer counts.
Real-time preview only. In production ray-tracing / path-tracing pipelines the same material can look tremendously different due to multi-bounce light transport.
