Lamination Stack-Up

Aggregate multi-layer film metrics from a layer bill of materials.

Editable layer list (name, thickness µm, density g/cm³, refractive index n, transmission %) seeded with three default layers (Hardcoat 5 µm / PET 50 µm / Adhesive 10 µm). Computes total thickness (Σ µm), areal weight (Σ µm·density g/m²), single-pass stack transmission (∏ T_i), and thickness-weighted mean RI. Layers can be added or removed; layer table mirrors the inputs with monospaced numerics.
