Which risk increases when a thin-film coating on analytical optics experiences localized thickness variations?

💡 Explanation

Thickness variations alter optical path lengths. Therefore, localized changes disrupt destructive interference, leading to increased undesirable constructive spectral interference because non-uniformity spoils the intended cancellation rather than minimizing reflection under consistent conditions.
