1. By varying the incidence angle the various contributions can be identified. 2. This feed in incidence angle is the ( half ) acceptance angle: 3. The deviation angle first decreases with increasing incidence angle , and then it increases. 4. Non-normal incidence angles also usually cause the reflection to be polarization-dependent. 5. As for AR coatings, HR coatings are affected by the incidence angle of the light. 6. Spectralon can partially depolarize the light it reflects, but this effect decreases at high incidence angles . 7. With these, it is possible to curtail reflection for a broad band of frequencies and incidence angles . 8. The limited phase-matching bandwidth of the crystal causes the generated wavelength to vary with incidence angle . 9. The second function of the SHG crystal is to act as the spectrometer by converting vertical incidence angle into wavelength. 10. The probe beam is coupled into a resonant mode and the coupling efficiency is highly sensitive to the incidence angle .
