Which mechanism causes spherical aberration when focusing a laser?

💡 Explanation

Refraction angle differences across the lens surface induce varying focal points resulting in spherical aberration because refraction determines the angular deflection; therefore image quality degrades with thick simple lenses rather than diffraction or polarisation effects.
