Aberration Types

  • Spherical: Focus depends on ray height
  • Coma: Off-axis asymmetric blur
  • Astigmatism: Different focus for tangential/sagittal
  • Field Curvature: Image surface curvature
  • Distortion: Image shape distortion

Correction Methods

  • Achromatic: Corrects 2 wavelengths
  • Apochromatic: Corrects 3+ wavelengths
  • Aspheric: Non-spherical surfaces
  • GRIN: Gradient index materials
  • Diffractive: DOE elements

Quality Criteria

  • Excellent: Strehl > 0.8
  • Good: Strehl > 0.6
  • Acceptable: Strehl > 0.4
  • RMS < λ/14: Diffraction limited

⚠️ Optical Design Safety

Aberration Impact: Uncorrected aberrations can cause laser hot spots, beam distortion, and reduced processing quality. In high-power applications, aberrations can lead to optical damage. Always verify aberration levels are within specifications for laser damage thresholds and application requirements.
