Optical properties by material type.
| Material | Bond Albedo ρ | Mixing Coeff. β |
|---|---|---|
| Aluminum | 0.85 | 0.25 |
| Thermal Foils/MLI | 0.26 | 0.25 |
| Solar Panels | 0.075 | 0.25 |
| Metals | 0.70 | 0.25 |
| Other Materials | 0.425 | 0.15 |
| Paints | 0.80 | 0.80 |
| Carbon/Kevlar/Glass | 0.50 | 0.15 |
| Unidentified | 0.15 | 0.15 |
Notes. Bond albedo ρ values range from 0.075 (solar panels) to 0.85 (aluminum). The specular/diffuse mixing coefficient β characterizes the fraction of specular vs. diffuse reflection, with β = 1 representing pure specular reflection and β = 0 pure diffuse reflection. Values represent midpoints of measured ranges from spectroscopic studies of retrieved debris samples.
