We provide a spectral analysis of an AdS Schwarzschild black hole near its photon sphere. We find that quasinormal modes near the photon sphere reflect the AdS boundary, resulting in a peculiar spectral pattern. Our large angular momentum analysis owes to an analogue to solvable Schr\\\"odinger equations such as an inverted harmonic oscillator and the P\\\"oschl-Teller model, with a Dirichlet boundary condition.
