| Excitation Type | Measured Attenuation (dB) | Repeatability (%) |
|---|---|---|
| Light-sheet skew rays (collimated) | 34.9 (20.0°, 12.5 µm) | ~5 |
| 32.0 (17.0°, 112.5 µm) | ||
| Meridional rays (collimated) | 30.2 (21.5°, 0 µm) | ~5 |
| Skew rays (collimated) | 21.2 (20.0°) | ~13 |
| 17.2 (15.5°) | ||
| Focused rays (tilted, centered) | ~19 higher than normal-incidence (1.7°) | N/A |
| Focused rays (centered) | 8.5 (1.7°) | ~3 |
| Normal-incidence rays | 0.9 (0°) | ~13 |
