← ScienceWhich safety outcome ensures maximal attenuation if a pulsed laser welds two mirrored steel plates?
A)Use Brewster window polarizer optics
B)Employ divergent beam collimation optics
C)Apply polarization-sensitive eyewear coating✓
D)Increase repetition rate of emission
💡 Explanation
Applying polarization-sensitive eyewear will yield increased attenuation because the Brewster angle effect allows only radiation of one polarization to pass. Therefore, the eyewear reduces incident light via polarization, rather than by diffusion, which would let hazardous light through.
