← ScienceWhich risk increases for an AR-coated telescope objective at steeper incidence angles?
A)Decreased destructive interference effectiveness✓
B)Increased chromatic aberration residuals
C)Enhanced Fraunhofer diffraction effects
D)Amplified stimulated emission threshold
💡 Explanation
Decreased destructive interference effectiveness occurs because an anti-reflective coating relies on thin-film interference at specific wavelengths and this interference is optimized for a narrow range of angles; therefore, performance degrades at steeper angles rather than other angular distortions increasing at high angles.
