⚠️ 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.
